I went to New York out of college, and in my day, we were told that was the way you became a good actor. You don't go to Hollywood, you go straight to New York and work in the theater. So that's what most of the people I knew did.

Generally, I have to be able to get the lines out of my mouth without making a mistake before I go to sleep.

I tended to do a lot of shows that were ahead of their time and didn't run very long.

It really was not that difficult a process, because I was playing [Data from Star Trek] something that doesn't exist. So it was really based on... Imagination was the key element in that, and whatever I could think of, I could do, because there was no precedent for it. It wasn't like someone was going to say, "Well, an android would never do that." They didn't know!

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.

There's such a grand fraternity of actors who've played the Joker, not the least of whom is Mark Hamill, who voiced it for so long and was so great. I did it one time and... I've gotten some feedback on it from people who've seen it and really enjoyed it, but I don't know.

When I get to work with people I admire, it's such a bonus, so it was an easy sell when I got this phone call asking, 'Will you do this thing with David Strathairn?'" Also, they didn't ask me to audition, which is another bonus. But they said, "All your scenes will be with David," and I said, "I'm there!"
