Big list
Barfly - About Charles Bukowski alter ego Henry Chinaski boozing, bar brawling, and womanizing. It was alright, not as good as I wanted it to be.
Frequently Asked Questions about Time Travel - A very funny British movie about 3 bar buddies time traveling.
Phantom of the Paradise - Campy 70's take on Phantom of the Opera and Faust.
Falling Down - Has held up very well.
The Thirteenth Floor - Like the Matrix only less convoluted and no crazy kung fu. Worth a watch.
Wet Hot American Summer - One of the strangest comedies I've ever seen. Kind of hit or miss but hilarious when it works.
