Any changes that I made to my line, I asked if I could make them, which I do in every movie. So far everybody's been gracious enough to say yes. The only improvising I do is in the movies I do with Chris Guest, which is what we do.

I've made a way to allow myself to do big films, small films, dramas, comedies, action films, horror films, or whatever interests me, as a movie-goer. I like watching myself in movies. I want to choose movies that allow me to enjoy myself, the way that I want to entertain myself.

It's often hope, hopeful movie making. You're always looking for catchphrases. That's always funny, when you're looking for that future line. "Uh oh, future line. Okay."

If you are a Jedi, just understand something: people are going to be chasing you. The Jedi Council of every city you enter is going to be chasing you. I've been accosted by the Jedi Council in Rio and everywhere else.

I did play a dentist in Waiting for Guffman. I wrote the speech at the conference. In the original script, when it got to that scene, it was, 'Thank you very much. Good night.' Literally. I just thought, 'He keeps talking about this speech. The keynote address is the big thing in his life and this is too important to say, "Thank you. Good night." I think we have to see and hear him doing what he does.' So I got together with my dentist and we worked through a few things.

Those are the rules. To improvise in a movie with other people, when they're following a script, everybody has to know what's going on. I think a line or two we might change. Certainly, I do. But I wouldn't call it improvising. I'd call it fudging the lines.

Long Kiss Goodnight has a huge cult following. They could make another version of that movie right now and make a lot of money.
