There is a THX commerical that plays in theaters before the film. In it they have various audio/sound bytes from different movies. Every time I hear it I try and guess where the clips are from. The THX website actually lists them all. I had previously identified the "well well well" from Die Hard, "1.21 gigawatts!'" from Back to the Future, "I will strike down upon thee.." from Pulp Fiction, and "Smokin'!" from The Mask. But the other 13 I didn't catch. Unfortunately I can't seem to find the actual audio anywhere on-line, but here's the list of movies the clips are from, in order:

Apocalypse Now
Jurassic Park
Die Hard
Jurassic Park
Nightmare on Elm Street
Star Wars Episode 1
Fight Club
Alien
Star Wars Episode 1
Pulp Fiction
Back to the Future
Lord of the Rings
