I do feel that movies and music do have the power to slightly influence a person's decision. I believe that if violence is not in a person, then the film is not going to encourage them.
I think that Mos Def is the best actor, but when you talk about rappers in films, I don't really think the quality of the acting is most important because most rappers are put in movies because of the personality and people want to see that.
Action films are emotionally and physically draining, and you're dirty and sweaty. In a romantic comedy, you have to have your fingernails perfect, you're in air-conditioned rooms the whole time.
