I think most actors go into the business thinking: "I can play everything. Why can't I play a black woman? Just give me a chance." Then you grow up and realize it's probably better that they cast an actual black woman. As I got older, I realized that my life experience, what I really had, was always going to be more valuable than what I pretended to have. Before
Will & Grace (1998) started, I had known plenty of gay men, and had been called names since I was in second grade. So I had enough of my own experiences to bring to it. It's harder to play a murderer. I would never kill anyone.
...I wasn't uncomfortable with any of the physicality that came with it: of looking at a guy and coming on to him, or thinking he was attractive.
