As a character actor, I've learned that you have to watch yourself because nobody else is watching. Nobody is concerned with you.
I'm a character actor. Nobody's ever seemed to think of me as a leading man. I'm 6'6''. I've got a big nose. I'm gangly. I've got crooked teeth. That's certainly not Brad Pitt. I'm still around and alive, so if they need older guys, I guess they're thinking of me.
My definition of a character actor is - they never get the girl.
I always change my words in everything I do. I make the language fit, because I know the character from the inside out. Often character actors are not in a position to do that, but I do it. I don't change any cue and I never change anybody else's lines, but I make my own words fit my mouth.
