As an actor, you're always at the service of somebody else's vision. In a play, it's more of the director's vision, and he or she's got their hands on you all the way up to opening night, and if it's a film, there are even more people.
This is a career about images. It's celluloid; they last for ever. I'm a black woman from America. My people were slaves in America, and even though we're free on paper and in law, I'm not going to allow you to enslave me on film, in celluloid, for all to see.
