One of my coworkers has been raving about "No Country for Old Men," so I'll probably go to see that. I also want to see "American Gangster" just for Russell Crowe's feathered 70s haircut. Speaking of 70s haircuts, I just watched "Dodgeball." Ben Stiller and his hair are a scream! (Yes, I like mental popcorn, especially if it involves Rip Torn.)
No Country for Old Men looks great! I really like the Coen brothers' films.
Barton Fink was the first I saw of theirs, and had to keep watching em after that.
