List of Legends elements in the films

C-canon elements from licensed Expanded Universe creators have been known to appear in the Star Wars films, mainly the Prequel Trilogy. Most of these are brief, cameo appearances, almost taking the form of Easter Eggs, but others are more substantial.

The Prequel Trilogy has also many references to names and elements introduced in Star Wars: Droids due to Ben Burtt's large involvement in both, not the least to mention, the cameo by himself as Ebenn Q3 Baobab.

Episode I

 * The name Rodian appeared for the first time in Galaxy Guide 1: A New Hope, but was used in the Prequel trilogy in scripts and production notes.
 * The Force Speed ability, used by Qui-Gon Jinn and Obi-Wan Kenobi to evade droidekas, was first created for the West End Games Star Wars Roleplaying Game
 * The name "Coruscant" was originally used by Timothy Zahn in the Thrawn trilogy of novels. Lucas was going to include the capital world of Had Abbadon in Return of the Jedi, but adopted Zahn's name for Imperial Center when presenting the planet in the Special Edition and prequel movies.
 * The Aurebesh that appears, is the one created by West End Games for Star Wars: The Roleplaying Game (in turn based on meaningless characters appearing in the Original Trilogy).
 * The acceptance of Hutts as a species, rather than a gangster title, was also new to the film.
 * "Boonta Eve Classic" resembles a race known as the "Boonta speeder race" where the droids ends up in the fourth episode of the Star Wars: Droids series A Race to the Finish.
 * Darth Maul's double-bladed lightsaber was a design originally seen wielded by Exar Kun in the Tales of the Jedi: Dark Lords of the Sith and Tales of the Jedi: The Sith War comic books.
 * It is not known if the following were intended to be EU references all along, or were later retcons and EU extrapolations:
 * Prince Xizor appears as a spectator at the Mos Espa Arena. A Micro-Machines model of the Shadows of the Empire villain was used to populate the crowd, possibly randomly, without canonical significance.
 * Toong, the species of Ben Quadinaros, was mentioned in Droids, while his planet, Tund, was first mentioned in the Adventures of Lando Calrissian
 * Theelin species, by the appearance of Diva Shaliqua. The species first appeared in Dark Empire (note that another Theelin has already appeared in the special edition Return of the Jedi, see below)
 * Ebenn Q3 Baobab of the Baobab family introduced in Droids. It was a minor cameo by sound designer Ben Burtt

Episode II

 * Aayla Secura appeared as a significant, albeit minor, character in the movies. She was introduced in Star Wars Republic: Twilight released after the Phantom Menace. George Lucas liked her illustration and decided to import her.


 * Action VI Transports, initially appeared as the Wild Karrde in Heir to the Empire, they also arrive at the Theed Spaceport in Attack of the Clones.


 * The planet Rishi, introduced in Dark Force Rising, was given a mention via the Rishi Maze in Attack of the Clones.


 * The swamp planet of Bogden is a planet visited by the droids in the series. In Attack of the Clones, Jango Fett says that he was "hired by a man named Tyranus on the moons of Bogden."


 * Dex's Diner has a strong similarity to the diner in an episode of the Droids series.


 * The region of Coruscant in the scene where Dooku arrives and meets with Sidious, resembles the Coruscant scenes in the alternate Dark Side ending of Jedi Knight: Dark Forces II. Note, however, that in JK the Imperial Palace appears instead of the LiMerge Power building.


 * Anakin Skywalker's use of Jar'kai near the end of the Episode II: Attack of the Clones was been first seen in Jedi Knight: Dark Forces II.


 * It is not known if the following were intended to be EU references all along, or were later retcons and EU extrapolations:
 * San Hill is identified as a Muun from Muunilinst, a planet first mentioned in Specter of the Past.

Episode III

 * A segment of music from the Shadows of the Empire soundtrack was used in the opening sequence music by John Williams.
 * The form of Force Grip as appears in the scene with Darth Tyranus and Obi-Wan (with immobilizing and lifting the target), first appeared in the Jedi Knight games.
 * Anakin Skywalker's double-lightsaber decapitation of Tyranus is inspired by Luke Skywalker's similar defeat of Shimrra in The Unifying Force.
 * Plo Koon's Delta-7 Aethersprite-class light interceptor has the same paint scheme as the Azure Angel.
 * Quinlan Vos mentioned (as 'Master Vos') by Obi-Wan Kenobi in the Jedi briefing room. Vos is an EU character (who in turn was based on a background extra seen at the Mos Espa café in The Phantom Menace). A cameo appearance of this character was planned but not filmed.
 * The sinkhole grottos of Utapau bear a striking resemblance to the pirate caves on Tarnoonga as seen in the Droids episode, The Pirates of Tarnoonga
 * The wheel bike, the vehicle of choice for General Grievous, when in a chase with Obi-Wan Kenobi on Utapau, was Jann Tosh's vehicle and was seen in the Droids animated series as confirmed by StarWars.com
 * Tsui Choi was about to appear in the movie, but the scripts were altered and didn't make it in.
 * It is not known if the following were intended to be EU references all along, or were later retcons and EU extrapolations:
 * The Massassi frieze in Palpatine's office depicts a battle of the Great Hyperspace War, described in the Tales of the Jedi comics. However, it is possible that when designed, it was intended to represent that Battle of Ruusan which was invented along with Episode 1.
 * Baron Papanoida is identified as a Wroonian. Wroonians appeared first in issue seven of the Marvel Star Wars comic series.
 * Nee Alavar, a background character, was identified as a Lorrdian. The Lorrdian people first appeared in the novel Han Solo's Revenge.
 * Padme Amidala says, "this war represents a failure to listen." The character Mira says the exact same sentence in Jedi: Count Dooku.

Episode IV
The Aurebesh that appears in the original trilogy is nonsense characters. West End Games created an original signification with English letters for Star Wars: The Roleplaying Game based on those characters. This new alphabet has been used in prequel trilogy and the remastered original trilogy
 * Swoop bikes from Shadows of the Empire. In the Special Edition scenes added to A New Hope, a swoop bike scares a ronto.
 * The Outrider (also from Shadows of the Empire) and with it, the YT-2400 freighters in general. Minor cameo, seen from distance lifting off from Mos Eisley, in the special scenes added to A New Hope for the Special Edition.
 * ASP-series droid, also appeared in Shadows of the Empire.

Episode V

 * Boba Fett, who first appeared in The Star Wars Holiday Special in 1978, plays a major role as the individual who takes Han Solo to Jabba the Hutt. Note however that Holiday Special is an exceptional case since it was written by Lucas himself.

Episode VI

 * Theelin species, by the appearance of Rystáll Sant. The species first appeared in Dark Empire
