Basically, my deal is that I choose roles based on three criteria. One is the role, obviously, if it's something that speaks to me. Two is, are they gonna pay me? And three is, who am I gonna work with? And, really, if one of those is there, I'm pretty likely to do it, but it's particularly important to me who I'm going to work with, 'cause that's part of the joy.

I know a guy who writes on the show, it was his episode, and he called and said, "Would you do it?" And I said, "Yeah." There's not really much else to tell, except that I was thrilled to be on The Simpsons, because it's one of the greatest series in the history of television.

It wasn't exactly a cattle call. I had an agent, and they were seeing people for the parts, so my agent said, "Here's the script, see if there's anything that speaks to you." And I did, and I called my agent and said, "I think this character Data is kind of interesting," and she said, "Well, okay, I'll get you the appointment with Junie Lowry." I had to read with the casting agent first, 'cause nobody really knew me then. Then after that, I had, I think, six different auditions for the role. And finally it was me [on Star Trek].

The character of Brent Spiner. We certainly collaborate on the concept of that, but he basically writes the script, then it's sort of a combination of his voice and my voice.

Having spent so much time in a fictional world, I prefer to read about the real world

Of those, the only one that really stands out for me is Tales From The Darkside, for a couple of reasons, one in particular being who I got to work with on it, which was Eddie Bracken. I mean, what a man. Someone who's done Preston Sturges movies, and I actually got to work with him? And he was great.

I think it was somewhere around age 3 when I fell down the stairs at my house, and I got up and did a Jerry Lewis impression and got a big laugh. And I thought, "Oooh, I like that. I think I need to do this for a living!"
