I don't think there's a short of young black male actors, just good material for them to act in!!!
Everyone wants to be a gangsta or a comedian...we don't produce epic films that feature blacks [male or female].
But, white producers and director pride in their work when it comes to their history, for instance, Troy, Alexander, Queen Elizabeth and just to name three out of many.
The only epic film ever made about a real African King played by a black actor [who was unknown] was Shaka Zulu...and it was writen, produce and directed by whites.
Like DP said there's a lot of black talent out there, just check out the film festivals, but no one tries to touch making films beyond topics such as salvery, rap music, honoring some sports figure and gangsta features when it comes to us....
