Requiem for a Dream - This movie is fucked uuuuuup mann! So scary, and the old lady is fucking wacked out! Cinematography is incredible, that or it was a good pick.
Alice in wonderland - So trippy, disney is on drugs!
Half Baked - cuz duh
Night of the Living Dead - original version in black and white where they blow the shit out of zombies for an hour and they kill the nigger at the end.
Double Impact - the one where Jean Claud Van Dam plays himself and his identicle twin and they kick the shit out of asians. With lines like "hey, if you don't get out of my way you will be in de fish tank at de bottom wit de fishes." you simply can't go wrong!
Yeah, that's my list, oh and any Schwartzenegger movie, I reccomend Commando, hahhaaha the bad guy is such a fuck ass!
