"Execute Order 66."
―Darth Sidious — (audio) Listen (file info)[1]

Order 66, also known as Clone Protocol 66, was a top-secret order identifying all Jedi as traitors to the Galactic Republic and, therefore, subject to summary execution by the Grand Army of the Republic. The order was programmed into the Grand Army clone troopers through behavioral modification biochips implanted in their brains, making it almost impossible for the clones to disobey the command to turn against their Jedi Generals. The Kaminoan scientists who designed the clone troopers believed it was only to be used as a contingency protocol against renegade Jedi. In secret, Order 66 was the means by which the Sith intended to bring about the long-awaited fall of the Jedi Order.

During the Clone Wars, the Sith agenda was progressing relatively unnoticed until a premature activation of Order 66 resulted in the death of General Tiplar at the hands of CT-5385 "Tup," a defective clone whose malfunctioning chip caused him to turn against his Jedi officer. The incident led ARC trooper CT-5555 "Fives" to conduct his own investigation into the matter, believing the incident to be a Separatist plot against the Republic. On the galactic capital Coruscant, however, he learned that the chips conditioned the clones to become hostile against the Jedi. Furthermore, he discovered to an extent Supreme Chancellor Sheev Palpatine's involvement in the conspiracy and attempted to assassinate him. Fives told what he knew to his Jedi superior Anakin Skywalker, but before the clone could prove it, he was killed by clone shock troopers of the Coruscant Guard.

The plan continued apace for the remainder of the war, although the Jedi High Council had grown increasingly wary of the Chancellor's motives. In 19 BBY, a group of Jedi Masters sought to arrest Palpatine upon learning his true identity as the Sith Lord Darth Sidious. When their efforts failed, Palpatine used the incident to frame the Jedi Order for treason and, as such, directed the clone army to execute their Jedi commanding officers in accordance with Order 66.

Across the galaxy, thousands of Jedi were killed by their own troops while the Chancellor's new apprentice, the Sith Lord Darth Vader, led the 501st Legion in a direct assault on the Jedi Temple of Coruscant. With the exception of a few surviving Jedi, such as Grand Master Yoda, Jedi Master Obi-Wan Kenobi, former Padawan Ahsoka Tano and Jedi Knight Kanan Jarrus, the Great Jedi Purge was largely accomplished through the initial activation of Order 66. Even after the initial onslaught, Order 66 still stood, and all Jedi, even people who might be Jedi, were to be killed on sight. Sidious would go on to consolidate his reign as Emperor of the Galactic Empire, ruling for decades until the prophecy of the Chosen One came to pass, marking the end of the Sith's rule and the restoration of balance in the Force by 4 ABY.


"Under this directive, any and all Jedi leadership must be executed for treason against the Republic. Any soldier that does not comply with the order will also be executed for treason."
―Clone Commander Rex, on the implementation of Order 66[5]

Through their bio-chip, a clone could be made to carry out Order 66

The clone troopers of the Grand Army of the Republic were programmed to comply with Clone Protocol 66 during the cloning process.[7] All clones were given a behavioral modification biochip[4] that could be activated by remote order via voice command; Supreme Chancellor Sheev Palpatine, for example, only needed to tell clones to execute Order 66, and the order was carried out.[1]

The biochip, when activated, would ensure total obedience in a clone, erasing existing biases and beliefs and instilling absolute loyalty to Palpatine. The order also forced the clones to view the Jedi as dangerous traitors who needed to be eliminated at all costs,[3] even their own lives.[8]

In some instances, the clone could resist the will of the chip and hesitate from executing his orders. This act took great effort, and resistance could not be maintained unless the organic chip was removed, which required external assistance in the case of Clone Commander Rex.[5] A few clones were immune to the order, but they were quite rare.[9] Genetically defective clones had a high probability of immunity to the command, due to their mutations interfering with the performance of the inhibitor chip.[10] However, the chip remained a danger as long as it was still inside a clone's head whether he was immune to the order or not, as outside factors such as head injuries could set it off.[9] Failure to comply with Order 66 was deemed an act of treason; as such, any clone trooper who defied the order was also subject to execution.[5]



The Sith in hiding

The Sith, an order of users of the dark side of the Force, was formed by fallen members of the Jedi Order after a war called the Hundred-Year Darkness.[11] Eventually, after many wars, the Jedi defeated and seemingly destroyed the Sith in the final, decisive conflict.[12] However, one Sith Lord survived: Darth Bane. Believing that the Sith's infighting had caused their downfall, Bane created a tradition called the Rule of Two where he chose to pass his knowledge on to only one Sith apprentice, who was required to kill their Sith Master in order to succeed them.[13]

For nearly one thousand years, the Sith thus existed in hiding, plotting their revenge against the Jedi.[12] Eventually, a human male from Naboo born Sheev Palpatine[14] became the apprentice of Darth Plagueis, and was dubbed Darth Sidious. He eventually took over as the Dark Lord of the Sith after murdering his master in his sleep.[1] In public life, Palpatine became a politician, serving as Naboo's Senator before eventually orchestrating an invasion of his homeworld in order to be elected the Supreme Chancellor of the Galactic Republic.[12] Sidious planned to fulfill the Sith's revenge plot by destroying the Jedi and transforming the ancient Republic into the Galactic Empire, and he set about engineering the eventual outbreak of the Clone Wars to do so.[1]

In 82 BBY,[15] the Jedi Padawan Dooku, on a mission to the planet Asusto with Jedi Master Lene Kostana and her Padawan Sifo-Dyas, had a Force vision of many possible futures during an encounter with the Presagers of Hakotei, a dark-side-using cult. Among the visions was a possible version of Order 66, with Jedi Master Jor Aerith being killed by Clone Commander Crane. However, not everything Dooku saw in that vision would come to pass.[16] Years later, Dooku left the Jedi Order, before falling to the dark side of the Force and becoming the Sith Lord Darth Tyranus, apprentice to Sidious.[17]

Warning signs

"Jedi. Good soldiers follow orders."
―Tup, prior to executing Jedi General Tiplar — (audio) Listen (file info)[3]

The Dark Lords of the Sith orchestrated the Clone Wars, including the implantation of the bio-chips that overrode their host's will with Protocol 66.

Around ten years prior to the outbreak of the Clone Wars, Jedi Master Sifo-Dyas ordered the clone army for the Republic,[17] having had visions of a future conflict. However, the Sith took over the project as part of their plot to destroy the Jedi Order, having Sifo-Dyas murdered by the Pyke Syndicate and concealing the true circumstances and location of his death from the Jedi.[18] Count Dooku, posing as a Jedi to the Kaminoan cloners, provided the Kaminoans with a bio-chip to be implanted into the clones during the early phase of their growth period. This chip contained the order the Kaminoans knew as "Clone Protocol 66"—which, when activated, would ensure total obedience in the clones and cause them to violently lash out against the Jedi.[4]

The Kaminoans, including Prime Minister Lama Su and Chief Medical Scientist Nala Se, believed the protocol existed as a contingency for rogue Jedi. Dooku, who was only known to the cloners under the alias of his Sith name, also convinced them that it was imperative the existence of the protocol and chips be kept secret from the Jedi, claiming it was what Sifo-Dyas had wanted.[4] The clone army's existence became known to the Jedi just before the Clone Wars when Jedi Knight Obi-Wan Kenobi tracked clone template Jango Fett to Kamino while investigating an assassination attempt on Senator Padmé Amidala.[17]

Early in the war, after the Ambush on Rugosa, Jedi Grand Master Yoda, while meditating, had a vision of Jek, one of the clone troopers who had accompanied him to the moon, at the moment Order 66 was issued, sensing Jek's emotions changing from disbelief and regret to a sudden urge to obey. However, Yoda's wariness towards Force visions and the intense disquiet he regularly felt around the clones due to their genetically engineered obedience prevented him from realizing the true import of the brief vision.[19]

Prior to the Battle of Umbara, Jedi General Pong Krell had visions of Order 66, the Great Jedi Purge, and the rise of the Galactic Empire. Subsequently falling to the dark side, Krell used his visions as justification for attempting to sabotage the battle so he could become Dooku's new apprentice. However, he was captured by the 501st Legion, who executed him for treason due to the danger that the remaining Umbaran forces might free him and learn vital military intelligence.[20]

Tiplar was killed when Protocol 66 was prematurely activated within Tup.

Towards the end of the war, Order 66 was almost prematurely exposed due to a malfunction in the biochip inside clone trooper CT-5385 "Tup," resulting in the clone alternating between his regular self and a trance-like state. The latter state caused Tup to shoot Jedi Master Tiplar during the Battle of Ringo Vinda, killing her instantly. The Republic retreated from their offensive, preparing to study Tup to determine what had happened. Learning what had happened to Tup, Dooku and Sidious feared that he would lead the Jedi to discovering their true plans for the war, including the clone protocol. The Confederacy of Independent Systems tried to kidnap Tup, but the Republic succeeded in bringing him to Kamino for further study.[3]

Uncovering the evidence

"The evidence is in here. It's—it's in here. It's in all of us, every clone."
"What is it?"
"Organic chips built into our genetic code to make us do whatever someone wants, even kill the Jedi. It's all in here."
―Fives and Rex — (audio) Listen (file info)[21]

The Kaminoans, trying to hide the protocol's existence, studied Tup and claimed that a virus had caused him to kill General Tiplar. Advanced Recon Commando CT-5555 "Fives"—Tup's best friend in the 501st—did not believe their claims, discovering the chip inside Tup, although he died after it was removed.[4] With the help of the medical droid AZI-3, Fives also discovered the chip inside his own head, and AZI-3 removed it for study before they both discovered that the chip was inside all of the clones. The Jedi brought Fives to Coruscant for further examination,[7] where Fives came face-to-face with Palpatine and discovered that the Chancellor was behind the plot. Palpatine framed Fives for an assassination attempt, discrediting the clone and causing the Jedi and fellow clones to pursue him. Despite knowing the truth, Fives, having been drugged into a state of aggression and paranoia, was unable to convince Anakin Skywalker or Clone Captain Rex, who were with him in the end, about the conspiracy or the Supreme Chancellor's involvement before he was killed by the Coruscant Guard. The Jedi Order accepted the story that a parasite had caused Tup and Fives' behavior, and that the chips were necessary to keep the clones mentally stable.[21] Rex was mostly skeptical of Fives' claims about the chips, but, unable to completely dismiss the theory, he filed a confidential grievance report about the chips possibly having a hidden purpose, although he was aware it was likely to be ignored.[5]

Yoda's vision of Jedi fighting clones

Later, the Jedi discovered that the Sith were behind the creation of the Grand Army of the Republic, as Count Dooku—under the name Tyranus—had selected Jango Fett as the genetic template for the clones and had worked with the Kaminoans to create the army after it was ordered by Sifo-Dyas. At the insistence of Grand Master Yoda, who testified to the clones' loyalty and valiant service, the Jedi High Council chose not to disclose the conspiracy to the public or even the Supreme Chancellor, believing that the Republic would lose the public's trust if it became known that Dooku was involved in the creation of the clone army.[18] Shortly thereafter, Yoda went on a journey to discover the secrets of immortality, and, on Dagobah, saw a vision of what would become Order 66.[22] Throughout his journey, Yoda came to accept that the Jedi would likely lose the Clone Wars, though he did not know how. He did, however, believe that the Jedi would still triumph in the long run.[13]

After learning from members of the Grysk species, which was unknown in most of the galaxy, that the metal cortosis was resistant to lightsabers, Dooku and Sidious attempted to acquire supplies of the resource from the planet Mokivj in an operation headed by Duke Solha. The Sith hoped to make clone trooper armor containing the metal and supply it to the clones who would carry out Order 66. However, the operation, carried out under the auspices of the Separatists, was foiled by Skywalker and a temporary ally, Senior Captain Mitth'raw'nuruodo of the Chiss Ascendancy. Skywalker believed the cortosis armor had been intended for a potential infiltration of the Republic's ranks.[23]

Sometime after the Battle of Anaxes,[24] 501st Legion clone medic Kix began to question the details surrounding the event which had led to Tup killing Tiplar. His subsequent investigation led him to discover that Fives had in fact been telling him the truth when he had first told Kix about the Jedi and the clones being framed and that the biochips implanted within the clones could indeed compel them to kill the entire Jedi Order. Before he could share his suspicions, however, he was kidnapped by forces sent by Dooku. He was subsequently tortured, but his denials about having leaked the information failed to convince his captors. He was then brought onto the Separatist cruiser Obrexta III and inserted into a cryo-cycle stasis pod for the journey to Serenno. As the cruiser was en route, however, it was ambushed by Republic forces. After sustaining heavy damage, the battle droid B1-CC14 made the decision to jump through hyperspace to a random sector to ensure Kix would stay out of enemy hands. The jump brought them to the desert planet Ponemah Terminal, with the Obrexta III crashing into the planet's dangerous south polar region, where it would lay undisturbed for decades.[25]


"How widespread is this?"
"Ahsoka, it's all of us. The entire Grand Army of the Republic has been ordered to hunt down and destroy the Jedi Knights."
―Ahsoka Tano and Rex — (audio) Listen (file info)[5]

Aayla Secura was among many Jedi who were betrayed by their clone troopers as a result of Order 66.

With the secrets of Order 66 secure, Sidious and Dooku continued with their plans during the Clone Wars. By the war's end, public support for the Jedi had weakened due to their management of the conflict,[26] while Palpatine remained a popular figure. Palpatine covertly disposed of Dooku during the Battle of Coruscant, and with Kenobi engaging General Grievous on Utapau, the Jedi hoped the war's end was imminent. However, Palpatine revealed himself to Skywalker as the Dark Lord of the Sith in an effort to seduce him to the dark side as his new apprentice. When Skywalker informed Jedi Master Mace Windu of the Chancellor's identity, Windu assembled a team composed of himself, Kit Fisto, Agen Kolar, and Saesee Tiin to arrest Palpatine. Their attempt led to a lightsaber duel in which Palpatine killed all four of the Jedi, and Skywalker turned to the dark side.[1]

Palpatine used the duel as a pretext to declare that the Jedi were traitors, ones who had attempted to assassinate him and take control of the Republic for themselves. The Chancellor issued Order 66 to various clone officers across the galaxy, while Skywalker—now the Sith Lord Darth Vader—was sent to kill the Jedi within the Jedi Temple, thus launching[1] an unprecedented and galaxy-wide massacre.[27] Thousands of Jedi throughout the galaxy were killed, including Ki-Adi-Mundi on Mygeeto, Aayla Secura on Felucia, Plo Koon in the skies of Cato Neimoidia, Stass Allie on Saleucami,[1] Depa Billaba on Kaller,[10] Jaro Tapal in the Bracca system,[28] and even Jedi younglings.[1] As part of the execution of Order 66, the elements of the 481st Legion were sent to the planet Ilum to secure the Jedi Temple there and kill any survivors.[29]

Some officers, such as Clone Marshal Commander CC-2224 "Cody," received individual transmissions from Palpatine.[1] Afterwards, the order was broadcast on repeat through the Grand Army's communications channels to ensure that all troopers heard it.[10] Throughout the duration of the Empire, Order 66 was still active: all known or merely suspected Jedi were to be shot on sight.[30]


"The remaining Jedi will be hunted down and defeated!"
―Darth Sidious[1]

Enslaved in thought and action after the dispatchment of Order 66, clones of the New Order were celebrated for their part in the eradication of the Jedi.

The execution of Order 66 marked the destruction of the Jedi Order. Before the Galactic Senate, Palpatine told the galaxy that the Jedi were traitors who had attempted to kill him and seize power, and the destruction of the Jedi was greeted with applause by the Senate. Having amassed immense central authority during the war, and without the Jedi Order standing in his way, Palpatine transformed the Republic into the Galactic Empire and declared himself Emperor. Along with Vader, Palpatine's rule meant that the Sith plan was completed, and the Sith Lords once again ruled the galaxy.[1] Under Order 66, specifically section Codicil Nine, keeping dark side artifacts was made illegal.[31]

Most of the irregular unit Clone Force 99 were immune to the order owing to either genetic mutations or implanted cybernetics, with the exception of CT-9904 "Crosshair" — whose chip was amplified by the Empire to enhance its effects on him. The rest of the so-called "Bad Batch" deserted the Empire within days of its formation.[10] Crosshair would later remove his inhibitor chip but remained loyal to the Empire, believing that his squad had abandoned him to his fate.[32]

Few Jedi survived the onslaught of Order 66.[1] The Jedi Padawan Caleb Dume survived the initial attack on his life due to the sacrifice made by his master, Depa Billaba.[10] Sometime later he was captured by the clones who had killed his master, but avoided death once more due in part to the last-minute intervention of Commander CC-10/994 "Grey," who asserted his will and realized that something else had influenced his thoughts when he and his battalion had previously turned on Dume and his master. Shortly afterwards, Dume went into hiding and took the name of Kanan Jarrus,[33] giving up his identity as a Jedi for fourteen years before returning, with the crew of the Ghost, to rebel against the Empire.[34]

Although many targets of Order 66 were killed by their own soldiers, Ahsoka Tano escaped with the help of Rex, after removing his inhibitor chip to free him from the brainwashing.

Despite having left the Jedi Order, Skywalker's former Padawan, Ahsoka Tano, was also targeted by Order 66, due to having unofficially rejoined the Republic military to lead forces in the Siege of Mandalore.[35] When the order was given, Tano and now-Clone Commander Rex were onboard the Venator-class Star Destroyer[5] Tribunal,[36] en route to Coruscant to deliver the captured renegade Sith Lord Maul to the Jedi Council. Tano had a Force vision of Skywalker's fall, but only realized that something terrible had happened. Rex, receiving the command from Sidious, realized at that moment that Fives had been right about everything and resisted his chip long enough to tell Tano to "find" the late ARC trooper before succumbing to the order and attacking her.[5]

While brainwashed, Rex also ordered Maul's execution, but Tano saved the darksider's life so he could act as a diversion. Tano then found Rex's grievance report, subsequently capturing Rex and removing his chip with the help of three astromech droids.[5] The two of them escaped the Star Destroyer after Maul destroyed the vessel's hyperdrive, leading it to crash into a moon, which killed everyone still onboard. Tano and Rex subsequently covered their tracks and went into hiding in the Outer Rim, after taking the time to bury every victim of the crash they could find.[8][35] Becoming a fugitive from the Empire, which officially declared him killed in action, Rex[9] eventually met up with Commanders Wolffe and Gregor, who also had their chips removed.[37]

Jedi Master Quinlan Vos was presumed to have survived by the Empire, and was a priority target of the purge.[38] Former Jedi Master Eeth Koth survived by leaving the Jedi Order prior to its fall.[39] Zubain Ankonori, Nuhj, Khandra, and Mususiel all survived and went into hiding together at a Jedi shrine on Anoat.[40] Jedi Master Kirak Infil'a survived by taking the Barash Vow.[41] Jedi Master Luminara Unduli was captured, and later executed at the Spire on Stygeon Prime.[42] Obi-Wan Kenobi went into exile on Tatooine, along with Vader's infant son, Luke Skywalker; Vader did not know that Luke or his twin sister, Leia, had been born, so the twins were taken into hiding.[1] Yoda, meanwhile, went into exile on Dagobah.[43]

Jedi Archives librarian Jocasta Nu survived and tried to create a secret school to train new Jedi Knights.[38] Jedi Master Uvell also survived and entrusted a ship of Jedi artifacts to Antron Bach to preserve the Jedi Order.[44] Jedi Knight Cere Junda survived as well, although her Padawan, Trilla Suduri, was captured by the Empire and tortured into becoming the Inquisitor Second Sister.[45] Grogu, a youngling of Yoda's species present at the Jedi Temple during the siege, was rescued, but lost his memories of the exact events due to trauma.[46]

Jedi Masters Oppo Rancisis and Coleman Kcaj, as well as Ka-Moon Kholi and Selrahc Eluos, were all confirmed by the Empire to have survived Order 66; but they could not find them because of how well they had hidden.[39] Padawan Cal Kestis also survived Order 66 due to the sacrifice of his master, Jaro Tapal, who defended Kestis from the clones and gave him a chance to escape into hiding.[28] According to legend, Kira Vantala also survived the purge, which surprised the Grand Inquisitor when she confronted him on the planet Gaaten to stop the abductions of Force-sensitive orphans.[47]

Sometime after Order 66, Rex made contact with the Bad Batch and learned they had not removed their chips, as Tech had concluded they were not a danger. However, the persistent headaches Wrecker had been suffering[9] after recent head injuries[48] said otherwise. Rex insisted that the squad meet him on Bracca to remove their chips. Reactivating the medical bay of a downed Jedi Cruiser, Wrecker was being examined by Tech when his chip activated, while Hunter and Echo were telling Rex about how they had witnessed Order 66 being carried out on Kaller. Wrecker subsequently attacked the squad, taking out the adult clones quickly before chasing after the child clone Omega. She attempted to talk him down, but failed, although Wrecker was struggling against the chip. Rex stunned Wrecker in the nick of time, and all of the Batch's chips were subsequently removed, ending the chips' threat to the squad.[9]

Under the influence of Ferren Barr, a clone trooper squad turned against a group of fallen Jedi.

During the Empire's subjugation of Mon Cala, Jedi Padawan Ferren Barr hid in Dac City and acted as an advisor to King Lee-Char.[49] There, he took several acolytes: Nipaltoo, Orvek, Rebb, Stell, Daren, and Verla. Barr was soon confronted by several of the Inquisitors and their troopers, whom he noticed were newer clones who had not yet had their control chips activated. After revealing them as former Jedi, Barr used a mind trick to force the troopers to execute Order 66 and attack the Inquisitors. The Tenth Brother, who was formerly the Jedi Master Prosset Dibs,[50] was killed in the ensuing firefight, along with the Ninth Sister having her right leg severed due to a betrayal from the Sixth Brother in an attempt to escape.[6]


"Our fellow soldiers, the clones, the ones we Jedi fought side by side with, suddenly turned and betrayed us."
―Kanan Jarrus, on Order 66[37]

For nearly twenty years, the Empire expanded without any significant Jedi opposition. Approximately five years before the Battle of Yavin, however, surviving Jedi, the few remaining in the galaxy, began to actively aid rebel cells around the galaxy, such as Kanan Jarrus for the Spectres and Ahsoka Tano for a larger network of rebel cells. Years later, Kenobi emerged from his exile and began training Luke Skywalker to become a Jedi Knight,[51] in the hopes that Luke would defeat Vader and Palpatine.[52] Kenobi was killed by Darth Vader aboard the Death Star,[51] leaving Luke to be trained by Yoda, one of the only known surviving Jedi. The two trained on Dagobah before Luke left to confront Vader.[43] Luke did not return until just before Yoda's death.[52]

The redemption of Anakin Skywalker led to the return of the Jedi.

Upon the Jedi Master's death, Luke became the last of the Jedi and set out to confront Vader once more, now having learned the truth that Vader was his father. During the Battle of Endor, Luke rebuffed Sidious' attempt to turn him and redeemed his father, with Anakin killing Sidious. The act of killing the Emperor resulted in Anakin's death, leading to the end of the Sith; through his death, Anakin fulfilled the prophecy of the Chosen One and brought balance to the Force. By confronting his father and saving him, Luke became the first new Jedi Knight in a generation, bringing about the return of the Jedi.[52] Thirty years later, Luke's nephew, Ben Solo, now known as Kylo Ren, carried out a similar incident, causing Luke to go into exile on the planet Ahch-To.[53]

Thirty years after the Clone Wars, Kix was finally awoken during the Race for the Lost Treasure of Count Dooku. He had been found by Sidon Ithano's crew and, now unable to save the Republic or Jedi, joined the pirates.[25] Around 30 ABY,[54] the former Jedi Padawan Naq Med found out that the Jedi were no longer being hunted, which allowed him to finally die peacefully, passing on his lightsaber and robes to his grandson Karr Nuq Sin.[55] Sometime following the Battle of Crait[56] in 34 ABY,[57] the pirate Hondo Ohnaka mentioned Order 66 in his book Galactic Explorer's Guide, claiming that the clones had risen up against their Jedi Generals. He recounted that Yoda and Luminara Unduli had survived but that the latter was arrested by the Empire and executed.[56]

Behind the scenes

"It is done, Master. The clone in question is now dead, and the Jedi still suspect nothing."
"Good. Destroy the evidence. When the time comes, no one will be able to stop our plan to execute Order 66."
―Darth Tyranus and Darth Sidious[21]

Order 66 first appeared in Star Wars: Episode III Revenge of the Sith.

The events of Order 66, namely the destruction of the Jedi Order, were first mentioned in the 1977 film Star Wars: Episode IV A New Hope, the first installment of the Star Wars original trilogy.[51] The destruction itself was first identified and depicted on-screen in 2005 film Star Wars: Episode III Revenge of the Sith, the final installment of the prequel trilogy.[1]

The backstory of Order 66 was provided in a four-episode arc in The Lost Missions of the television series Star Wars: The Clone Wars.[3][4][7][21]

Unused and rejected concepts

"I think it was a little more gruesome than you ended up seeing, you know. A lot of young potential Jedi ended up on the cutting room floor."
―Ian McDiarmid on the original version of Order 66[69]

Though first depicted in Revenge of the Sith, Order 66 was originally planned to start in the 2002 film Star Wars: Episode II Attack of the Clones.[70]

Quinlan Vos depicted in a deleted animatic from the earlier versions of the Order 66

In the first draft of of Revenge of the Sith, dated to April 13, 2003, the number of Jedi Knights who were killed was "more extensive" than the ones seen in the finished version of the film, though some animatics for these versions were made.[71] The following order in this early draft was taken from the book The Making of Star Wars Revenge of the Sith:

On Mygeeto, clones blast KI-ADI-MUNDI and SAESEE TIIN. On Saleucami, they kill KIT FISTO, BARRISS OFFEE, and ADI GALLIA. On Kashyyyk, MINA PODIA is gunned down-but YODA saves himself. On Cato Neimoidia, PLO KOON is blasted out of the sky, while an unnamed Jedi lies dead on the planet surface. On Felucia, AAYLA SECURA and QUINLAN VOS are silenced forever.[71]

Some other concepts featured in other drafts and versions of Revenge of the Sith included Boba Fett taking part in Order 66 by killing Mace Windu in an attempt to avenge his father Jango's death until George Lucas reorganized the entire story and felt that Fett would be "too young" and wasn't an essential part in the story.[71] For the deaths of Barriss Offee, Luminara Unduli and Shaak Ti, it was planned to use some unused footage of Nalini Krishan, Mary Oyaya and Orli Shoshan from Attack of the Clones.[72] In Ti's case, however, Shoshan filmed an earlier death for her in the film's beginning, though both scenes were cut from the finished film.[71]

Ian McDiarmid, the actor who played Darth Sidious in the films, stated during a panel appearance at Salt Lake City's FanX convention in 2018 that Order 66 was intended to be more gruesome than in the finished version of the film, but George Lucas toned down the scene from his original vision in order to avoid a harsher rating, and his decision was probably a good idea after all. Revenge of the Sith was ultimately rated PG-13, unlike previous films.[69]
