Sith Apprentice (2005)
Count Dooku (played by Christopher Lee in the real films) mentions looking for Peter Cushing - mention is also made of Lee's former jobs as Dracula and Saruman, and at one point, the character turns into a bat.
Count Dooku uses the "it's only a flesh wound" line to annoy Darth Vader
Vader lifts the line "The can be only one..." before killing Count Dooku and becoming the new Sith Apprentice
Count Dooku uses the famous "I'm not left-handed" gambit/dialogue from the movie.
Darth Maul's lines and his 'cut in half trick'
JarJar Binks, in pleading for his job, makes reference to making The Emperor's rise to power possible due to his actions in Episode II
Dooku attempts to quote Saruman from The Two Towers, the connection being both characters were played by Christopher Lee
Darth Vader performs an Irish dance number with stormtroopers, staged just like Riverdance
After the Vader/Riverdance parody, Vader is called "The Dark Lord of the Dance"
The entire film spoofs the setup and design of The Apprentice, but in the Star Wars universe.
Count Dooku's death in combat with Darth Vader in the parody is apparently exactly the way it will appear in the real film.
