Gangs of New York was awesome. Scorsese is a national treasure.
Life is Beautiful
To Live and Die in LA
Monty Python- Holy Grail and Meaning of Life
Gold Rush, Modern Times, City Lights, The Kid- all films by Charlie Chaplin.
Swingers
Napoleon Dynamite
Slacker
Run Lola Run
Mystery Train
These are all movies I'll watch multiple times.
edited to add: Troy, starring a baby-oil coated Brad Pitt, was the worst movie I've seen in the past year. Somehow they managed to turn a truly exciting story into silly, vapid mush. The script was ridiculous and the acting was bad, even by Brad Pitt's standards.
