Short answers, pulled from the story.
Robot Chicken: Star Wars is a 22-minute special episode of the animated comedy series Robot Chicken that aired on Cartoon Network's Adult Swim block on the 17th of June 2007. It was released shortly after the original Star Wars film's 30th anniversary. The episode was later released on DVD on the 22nd of July 2008.
A sketch from Robot Chicken's second season, in which Palpatine receives a collect call from Darth Vader about the Death Star's destruction, spread on YouTube and was eventually seen by George Lucas. Impressed by the parody, Lucas invited creators Seth Green and Matthew Senreich to Lucasfilm, where they were given permission to produce a full 30-minute Star Wars parody.
The cast includes Seth Green voicing the majority of characters, Seth MacFarlane as Emperor Palpatine, Mark Hamill as Luke Skywalker in the spoilers sketch only, Ahmed Best as Jar Jar Binks, Conan O'Brien as Zuckuss, Hulk Hogan as Abraham Lincoln, and George Lucas voicing himself. James Earl Jones was pursued for the role of Darth Vader but was unavailable.
The episode took three months to produce from script to completion. The writing staff spent three weeks developing material, the stop-motion animation team finished their work in two weeks at a rate of 12 seconds of footage per animator per day, and editing plus visual and sound effects took an additional two months.
Seth Green won the Annie Award for Best Directing in an Animated Television Production for the episode. The special was also nominated for Best Animated Television Production at the Annie Awards and received a Primetime Emmy nomination for Outstanding Animated Program (for Programming Less Than One Hour) in 2008, losing to the Simpsons episode "Eternal Moonshine of the Simpson Mind."
Two sequels were produced. Robot Chicken: Star Wars Episode II aired on the 16th of November 2008, and Robot Chicken: Star Wars Episode III aired on the 19th of December 2010.
