Sometimes I try to improve the language, the lines, or the delivery, but I don't ad-lib because I think that makes it really hard for everybody else involved.
I don't take trouble at all to conform a screenplay to my iconography. I don't say, "We can't do that - the audience wouldn't accept it." I try to take the limitations of what is required to play a leading character and then screw with them.
I try to preserve a certain amount of time away from the movies, so I don't allow time to do those smaller parts that might give me an opportunity to do more seemingly 'artful' things. Although, having said that, I don't feel any lack of noble purpose if I do a film that's commercial.
I have an attorney. I'm looking to be rich like Harrison [Ford]. I'm trying to have planes and do all that stuff.
Work hard and figure out how to be useful and don't try to imitate anybody else's success. Figure out how to do it for yourself with yourself.
