Phineas and Ferb: Star Wars

Phineas and Ferb: Star Wars is a one-hour special episode of the Disney Animation television series Phineas and Ferb that will air in summer 2014 on Disney Channel and Disney XD. The Star Wars-themed crossover was first announced at the annual San Diego Comic-Con International on July 19, 2013.

Official description
The episode's story begins a long time ago, in a galaxy far, far away -- in summer. Phineas and Ferb are living happily on Tatooine, just one moisture farm over from Luke Skywalker. They love simply hanging out and creating new adventures under the twin suns, however, they find themselves thrust into a global rebellion when the plans for blowing up the Death Star accidentally fall into their hands.

Now that fate has suddenly pulled them into the fight for freedom, they must go in search of a pilot who can take them to the Rebels so they can hand over the plans. Complicating matters, Candace -- the boys' sister -- has a Stormtrooper-like intent on "busting rebels" who chase Phineas and Ferb across the galaxy in hopes of retrieving the Death Star plans.

Meanwhile, back on the Death Star, Dr. Darth Enshmirtz, a low level Darth, has created a Force-powered "Sith-inator" that he plans to use against the Rebel Alliance. Agent P, working undercover for the Rebellion, is dispatched to stop him, but quickly gets trapped in carbonite. Then, things take a startling turn when Ferb is accidentally hit by the full blast of Dr. Darth Enschmirtz's "inator" and becomes...an evil Sith.

Behind the scenes
Dan Povenmire, one of the show's creators, first hinted at the crossover during an interview with TVGuide.com about the show's upcoming crossover with Marvel Comics, as he indicated that he had the Star Wars-themed episode in mind since Lucasfilm Ltd.'s acquisition by Disney in 2012. Robert Hughes confirmed that there would be at least five songs in the special.
