If I'm racist, don't think I would have directed shows like 'The Parkers' and 'The Wayans Brothers' or worked 41 episodes with Victoria Rowell on 'Diagnosis: Murder.'
Whenever you deal with science fiction you are setting up a world of rules. I think you work hard to establish the rules. And you also have to work even harder to maintain those rules, and within that find excitement and unpredictability and all that stuff.
