I had told my agents that I didn't want to do television. I can't believe I had that gall, looking back on it. I would never condescend to do TV, and then 'Taxi' called up for a guest spot in the first season. And my common sense kind of took over, I guess.

There were a couple times with close-ups where I tended to overact. I would use more of my face than I needed to. I learned how to be more subtle.

In a way, theatre is still my first love.

I meet people on the street who literally chose their careers because they saw 'Back to the Future' and decided they wanted to be scientists or astronomers or engineers.

Whether it's a very dramatic part or a comical role, I feel I need to create the same thing: a full-fledged, three-dimensional character that the audience can identify with.

I got a few speeding tickets when I was young, but I'm a little more like the turtle than the hare.

I was just very shy. I was never anxious to do talk shows, as I didn't know what to say. And I don't feel I have any inherent interest. But as I'm getting older, I feel I want to be able to share whatever I know if it means something to someone.

'Star Trek' came along fairly early. And I don't know what they saw in me that said Captain Kruge, because I hadn't done anything remotely like that, but it worked out.

Over the years, I have attended comic book conventions and met people that are die-hard fans; they'll come up and say, 'Clue' is my favorite movie of all time.' It has definitely resonated in some way with people and just continued to build up over the years considerably.

I really enjoy playing villains, whether they're realistic like Switchblade Sam or whether they're a bit more over-the-top like Kruge in 'Star Trek III' or Judge Doom in 'Who Framed Roger Rabbit.' It's sort of a license just to be as bad as the script allows you to be - you can just go for it and have fun.

I grew up on Charles Addams' cartoons, particularly 'The Addams Family,' and Uncle Fester was always one of my favorites.

We were all such odd characters, even though we were a really functional family, in a way, as eccentric and crazy as we were. And it was such a wonderful feeling amongst us of being a family almost. We were 'The Addams Family!'

The film I had the most fun in was 'Back to the Future Part III.' It had horseback riding, and all that work, all that training, was quite an experience.

I don't know if there are too many other trilogies with stories that have continued to captivate audiences like 'Back to the Future' has.

I didn't know where my career was going to go. Somehow, people sensed that I have certain talents and cast me in these bizarre, off-beat roles, which I have no regret about. I've enjoyed playing every one of them.

I guess nobody can teach you the knack, or whatever it is, that helps you come to life on stage.

The time and preparation before a play is something I really value, and it's something I learned in New York.

Some people have quick retention. I'm not one of those.

As long as I can keep remembering the lines and getting to the locations, I want to keep working as long as I can. I love it.

I'm not too picky. I'm not waiting, sitting around for the ideal and perfect role. I like to work, so I try to make the best of whatever opportunity comes up.

'Cuckoo's Nest' came along, and I was cast, and that was great, but it was my first film, so I felt like I was kind of walking around on the set as Walk-On A.

I was already committed to a play back in New York about Hans Christian Andersen, where Colleen Dewhurst was going to play my mother. I was excited about that, and I got this script called 'Back to the Future,' and I thumbed through it. Didn't pay a hell of a lot of attention.

'Cuckoo's Nest' was my first film, and I had wanted to do film for some time, but somehow I had not clicked. I would go in for interviews or readings, and I never had the sense that I was anywhere near what they were looking for.

Every role I get is always a challenge. I can read a script and say, 'Oh, I can do that!' and then when I start working on it, I suddenly realize that I had no idea what I was getting into. Then I have to really work hard!
