Ludacris IS a good actor. That guy is going to go far with that if he wants to. And I agree that Will Smith and Marky Mark have made far better actors than they did musicians. Mos Def is also a musician-turned-actor who had done some good acting work, and I think Queen Latifah will probably win an acting Oscar one of these days if she keeps up on her current acting trajectory and doesn't overdo the comic roles. I think it's interesting when they turn out to be multi-faceted and can do both things well. Wish Jessica Simpson would stay behind a microphone, though, until she gets a lot better at acting. She's too nervous an actress and has that irritating, self-conscious head-shake she does when she's speaking her lines. I think good actors have to be fairly smart and emotionally perceptive, and I'm not sure Jessica meets those qualifications.
