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.

I don't read Science Fiction.

John Logan was kind of wrapping up - "Well, thanks for coming in..." - and I thought, "Oh, God, this is over and I'm out of here, and I really don't want to leave."So I said, "Can I ask you a question?" He said, "Sure." "What movie do you think you've seen more than any other movie?" And he said, "Wow, let me think about that. I guess probably The Searchers." And I said, "Well, oddly, that's the movie I've seen more than any other movie." And I wasn't just BS-ing. It's true. It's my favorite movie.

And the basic sort of thrust of Star Trek being about equality and tolerance and things I believe in deeply.

The one on Fresh Hell is a little easier, because we make it up. It's a strange kind of hybrid of the real me and... Well, obviously it's me standing there, and it's my voice and my face, but it's also kind of filtered through Harry Hannigan's take on the character, the one he's writing.

John Logan pretty much does the Woody Allen thing of just bringing people in and meeting them.

As I get older and I get more of this dialogue and I lose more and more brain cells, it really does become the most difficult part of the job!
