I consider actors artists in their own right. I've always been a fan of Smith. When he was on Fresh Prince there were a few particularly dramatic episodes where he really impressed me. I had a feeling he was going to be like some of the great comedian-turned-Oscar nominees like Tom Hanks, Whoopie Goldberg, Robin Williams, Jim Carey, etc., and I think he's lived up to it.
I don't think this is as evident in his action films (and I'm not an action film fans), and I think he's a gifted comedy actor (even though movies like Men in Black and Bad Boys are not my taste, I think he was excellent in them) but I find his dramatic roles to include some outstanding performances, namely Bagger Vance, 6 Degrees of Separation, 7 Pounds, The Pursuit of Happyness. I wish he would take on more of these kinds of roles.
