Hair is very, very distinctive. I started that with that boxing movie I did, The Great White Hype. The director wanted me to look like Don King, and everybody knew who Don King was. But I didn't want to be Don King. I wanted the man to be Rev. Fred Sultan, so I decided to make him look like Julius Caesar. And from that point on, I just decided, I had this great wig-maker, so I just found hairstyles that I felt would be distinctive for every character. Like an adventure.

I think I've had my taste.I got to work with Sam [L.Jackson]. I can say I did it. I had my shot. I'd love to do something with [Robert] De Niro or Dustin Hoffman or Al Pacino. Those are guys I grew up watching. That would be wonderful. Now that I've gotten a taste working with a bona fide movie star, I think I'd be more prepared to go head to head with some of the big boys.

I trust most people. Not producers.

It was fun to be in a scene again with [my wife LaTanya Richardson]. We used to do plays together all the time. We hadn't really worked together since Losing Isaiah [1995]. That was kind of early on in both of our cinematic careers. Things have changed a little bit since then.

Sometimes one of my ways of choosing movies that I want to do is if it's the kind of movie I would have gone to see when I was a kid, and this is a movie I actually did go see, as a kid. And I think it will be exciting for audiences to see now.

I did play a dentist in Waiting for Guffman. I wrote the speech at the conference. In the original script, when it got to that scene, it was, 'Thank you very much. Good night.' Literally. I just thought, 'He keeps talking about this speech. The keynote address is the big thing in his life and this is too important to say, "Thank you. Good night." I think we have to see and hear him doing what he does.' So I got together with my dentist and we worked through a few things.

The only thing I've kind of missed is finding a really good western that I want to do, because I watched westerns a lot.
