To be honest, Kerry Washington and Taraji get better roles than Gabrielle and Sanaa. So I think that Gabrielle and Sanaa are the ones playing catch up i.e. Stuck doing shitty movies.I think what Anon meant was they don't get the love in the Black community, but they do get better roles and are better actresses. Taraji is on so many Oscar sites this year for The Curiosu Case of BEnjamin Button and she always have critically acclaimed performances and so does Kerry. So in the Mainstream film critics world they are a LOT more popular than Sanaa and Gabrielle. As far as coming up that's like saying that Cate Blanchett hasn't come up to the level of Jessica Alba. That's a WTF statement. Jessica is known more for her looks, but she is a terrible actress. Whereas Cate is known for her talents. Cate is the one getting critical acclaim and getting great roles while Jessica much like Sanaa and Gabrielle are stuck getting shitty roles. I do think that Cate, Taraji and Kerry would rather get decent roles than be on Sanaa, Jessica and Gabrielle's level. That's just my opinion though.

Viola is a great actress she's in Doubt with Meryl Streep and is currently the frontrunner in the Best Supporting actress race for the Oscars this year.

Don Cheadle is the shit nuff said and he is VERY famous. So I don't know what you meant about him having not come up yet.

Chiwetel is also the shit and a very versatile actor. He is making some major moves in Hollywood

Nate Parker is a newbie and is just getting started.

I love Will Smith no he isn't the most talented and HE said it himself but he is very charming.
