Nice list, CC. Especially Private Ryan, awesome flick.
Here's a few:
-Raising Arizona (and just about any film by the Cohen Brothers)
-U2: Rattle and Hum (best if you have a good sound system to run it through)
-A Clockwork Orange
-Full Metal Jacket
-Tommy Boy (stoned or not, just a good knee-slapping, laugh-your-ass-off movie)
-Koyannisquatsi (might have to order this one, although I have seen it on cable many times. Title is some ancient Hopi Indian word. It is basically some great cinematography of the world; natural wonders, landscapes, and some very tripping views of cities and man's impact on the world. No dialougue, just a soundtrack. A real mind-blower)
-The Band: The Last Waltz
-The Doors
-Platoon
-The Cook, The Thief, His Wife And Her Lover (again, may have to order, but it is worth it, as it will trip ya)
-2001: A Space Odyssey
-Alien (all are great, but I and II are best)
-Anything by Monty Python (although The Holy Grail, The Meaning of Life, and Life of Brian are top picks)
-Signs
I could go on and on, but these will definitely keep you entertained while your blazing. And they're pretty damn good even if you're not...Enjoy!
