I think we're all fans, and I understand the whole world of fandom, because I am a fan.

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].

We had lunch that day [with Chris Ellis], and I was talking about this idea. I toyed with it a little bit on Twitter in story form at one point. And he thought it was a great idea, and he thought, "Well, let's bring my friend Harry Hannigan in, who's a wonderful writer, and let's see if we can put something together."

It was kind of an amazing class. I went to the Strasberg Institute in New York for a little while after I got there, and I've never seen anybody who was in any of my classes there ever again. I mean, that's not to say they didn't become somebody. I'm not sure. I mean, Sam Jackson could've been in my class, for all I remember.

I had no idea I was part of what was going to be a big mega-hit. I thought I was doing a B sci-fi movie [Independence Day]. And, actually, it was Jeff Goldblum who looked at me one day and said, "You know, I think this is going to be really something." And I said, "Well, I hope you're right." And sure enough, it turned out to be.

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 think that Enterprise was getting better and better, actually, and if it had kept going, I think it would've turned into as good a show as any other in the Star Trek franchise.
