O Brother, Where Art Thou?
Disclaimer: I'm a bit sleepy so I don't want to watch a movie with too many long and drawn out slooow-moving scenes. Nothing against long drawn-out scenes, I just don't want to doze off.
edit - I think I'll watch O Brother based on the responses and save the others for when I'm more awake. thanks, gang!
