I'll take the easy road and start with Kevin Smith movies:
Clerks: The Death Star Conversation as well as "Chewbacca" song by supernova.
Mallrats: Silent Bob trying to use the force constantly.
Chasing Amy: The Star Wars racism speech.
Dogma: The Muse came up with the idea for Star Wars, as well as Jay's reference to the diner being like the Cantina.
Jay and Silent Bob Strikes back: This movie is chock so full of Star Wars references (including the title) it's self explanitory.
UHF: Stanley Spudowski's mop is a lightsaber.
Can't Hardly Wait: Two dorks playing Luke and Vader on the roof.
Swingers: Explaining how to use that "Jedi Mind ****" on women.
Free Enterprise: It's basically a geek movie, so they have a TON of references in this one. My favorite being the scene where they go toy shopping, and some kid tells them how to say "Xixor".
I think that's enough for a first contribution.
