Bump. I think it'd be nice to start this up again. I don't think I can really pick my favourite film since there are so many aspects by which you could judge a film. Visual appeal, entertainment, story, originality, etc. During the last couple months I've seen all of Kubrick's films and I've completely fallen in love with him. Each one of his films is like something you've never seen before. I also like Burton, Scorsese, Nolan, Spielberg, Fincher and many others I can't think of right now.
Some of my favourite films are (not in order):
Fight Club
One Flew Over the Cuckoo's Nest
Trainspotting
The Imitation Game
The Truman Show
Twelve Monkeys
Grand Budapest Hotel
American Psycho
Gladiator
Back to the Future
Django Unchained
Requiem for a Dream
Mr. Nobody
The Wolf of Wall Street
The Departed
Original Star Wars Trilogy
Lord of the Rings Trilogy
And literally everything done by Kubrick (except for his first feature film from 1953 Fear and Desire):
2001: A Space Odyssey
A Clockwork Orange
Dr. Strangelove
Barry Lyndon
Spartacus
Lolita
Paths of Glory
The Killing
Killer's Kiss
The Shining
Full Metal Jacket
Eyes Wide Shut
