Everything I do, I'm sort of half in, half out.

If people recognize me when I'm out in public, I'm very nice to them. I'm very nice to people even when they don't recognize me. I don't even mind if people come up to me while I'm eating dinner, but if they recognize me while I'm having sex, I refuse to sign autographs.

There comes a point when you've exhausted your opportunities playing good guys. I've been around long enough, I think I'm entitled to explore a bit. But what I saw there was an opportunity to play a character different from what the audience's expectation was. A chance to take their crude experience of me - of my iconography, if you will - and turn it on its ear at an appropriate juncture in the film to be useful to the process of telling the story.

As a matter of fact, that was a bit of a problem for me at the beginning of my career - the problem of identification. In The Conversation I played a character who was gay, so nobody recognised me from American Graffiti. When I did Apocalypse Now, after Star Wars, I played an intelligence officer of the American army. George Lucas saw the footage I had done and didn't recognise me until halfway through the scene.

I've never wanted to be the boss.

I think I did have a reputation for being grumpy. I don't think I'm grumpy. I have opinions. I have an independent vision. I am a purposeful person. But on a daily basis, I think I'm other than grumpy. I think it is a case where I am coming to do business and not there just to be flattered and cajoled and used.

I've never been bothered by proximity to special effects and I've never felt disadvantaged by them. They're all part of a movie, and when the movie's under control I don't feel upstaged by them.
