Jamie Foxx is in a good amount of movies now days. I think some people view him as the flavor of the month, but I believe he has staying power. He's in a movie that has yet to be released called Jarhead, it looks pretty good.
Yes, black actors do still die early in some movies, but there are a good amount of regular black actors although some of you guys may not know them:
Denzel Washington
Mario Van Peebles
Jamie Foxx
Regina King
Sam Jackson
Larenz Tate
Terrence Howard
Cedric the Entertainer
The Rock (I think he's half black, but I may be wrong)
Wesley Snipes
Taye Diggs
Nia Long
Halle Berry
Morgan Freeman
Will Smith
Jada Pinkett
Omar Gooding
Morris Chestnut
Vivica A. Fox
Michale Clark Duncan
Don Cheadle
Chris Bridges
This is not to say its still not hard for minorities to get work in Hollywood, I'm just saying there are more than just 2 or 3 regulars.
If anyone wants to see good movies with minorities (they're not just filled with minorities though), try Crash (DVD next Tuesday), American History X, A Time to Kill, Higher Learning, and a foriegn film called Brother.
