Last night I bought Fight Club and watched it for the first time. That is a bad ........ movie! Edward Norton is one of the best actors. He was awesome in both Fight Club and American History X. I want to go watch the 25th Hour soon.
Another good actor is Sean William Scott, because he has been funny in every single role I've seen him play. I've seen him in American Pie. American Pie 2, Jay and Silent Bob (him and Will Ferrell were the only two funny ones in this), and Final Destination.
Off the top of my head those are two of my favorite actors that aren't exactly mega-stars like Denzel Washington, Tom Cruise, etc...
As for actresses I can't really think of an actress that would make me go watch a movie just because she is in it. Not to say that there aren't actresses deserving of that, though.
yes, I'm very bored today...
