Let the geekdom begin...
Either of the modern Batman movies and Batman Forever (just cuz Jim Carrey is a BEAST)
Dumbo (IMO the three best hand-drawn animation sequences in the history of animation here)
Ocean's 11 (Pitt/Clooney edition)
Star Wars (original trilogy, pre-edit, theatrical release, Furry Jabba editions)
Star Trek (TNG and modern only)
Anything Disney except from the 70s and early 80s
Anything Pixar (yes, I'm an animation geek)
There are probably about a hundred others that I'm just forgetting ATM...
