Here's some oddball movies that I would recommend - odd being a fairly loose term...

Pi - B&W indie film
Pan's Labrynth (sp?) - Spanish movie, award winner fantasy movie
Tigerland - another older indie film about army bootcamp in the 60's. Very good acting considering the budget

I also enjoyed these more mainstream movies this year:

Casino Royale
The Illusionist
25th Hour
Beerfest (what can I say, I like to laugh)
The Black Dahlia
