A Clockwork Orange - the only perfect film I have ever seen
Twelve Monkeys - my favorite flick! Its got Bruce Willis, Brad Pitt both acting in roles almost opposite to what they normally do. Crazy plot, crazy direction, and all-around awesomeness.
Forbidden Zone - hands down the craziest thing I ever laid my eyes on
Raising Arizona - the funniest film ever made
Blade Runner - futuristic film noir, set only twelve years from now
Eternal Sunshine of the Spotless Mind - beautiful movie about relationships and the disintegration of the persistence of memory (wrap your head around that one)
Dead Alive - the only other romzomcom (romantic zombie comedy) next to Shaun of the Dead, also the goriest, grossest movie in the world
If I was banished to a deserted island with a portable dvd player, infinite batteries, and my choice of seven movies these would be it.
