If you've got the cash invest in the Stanly Kubrick Collection. Many great movies including: A Clockwork Orange, Full Metal Jacket, The Shining, 2001: A Space Odessy, Dr. Strangelove or how i learned to stop worrying and love the bomb, Lolita, and Barry Lyndon. Eyes Wide Shut isn't in the collection only his classics.

I'd also like to recomend: Scarface, Casino, Pink Floyd Live @ Pompei, Pink Floyd The Wall, Led Zeppelin The Song Remains The Same, Fight Club, Lock Stock and Two Smoking Barrels, Snatch, Pulp Fiction, The Big Leboski (sp?),
The Usual Suspects, Dogma, Jay and Silent Bob Strike Back, Bowling For Columbine, Fear and Loathing, and that's about all I can think of at the moment. poof poof

edit: oh fuck, how could I forget Half Baked THE GREATEST stoner movie of all time!
