I don't have any theories about acting, and I don't think about how to do it, except that an actor shouldn't take himself too seriously, and shouldn't try to make acting something it isn't.
It wasn't until I'd turned 50 and had been in the business 25 years that I realized I might actually have a career as an actor.
The only reason I'm an actor is that a lady pulled out of a parking space in front of a producer's office.
Acting is just common sense. It isn't hard if you put yourself aside and just do what the writer wrote.
I've been on the wrong end of violence, and I've done violence myself... I refuse to glorify violence in my movie and television roles.
