I wanted to be a forest ranger or a coal man. At a very early age, I knew I didn't want to do what my dad did, which was work in an office.

It doesn't interest me to be Harrison Ford. It interests me to be Mike Pomeroy and Indiana Jones and Jack Ryan. I don't want to be in the Harrison Ford business. I take what I do seriously, but I don't take myself seriously.

There are a lot of different paths through the jungle, but...the simplest thing you can do is make yourself useful. Be easy to work with, be a hard worker and help people get the job done. And do it with as much passion and quality as you can.

I was never that much a focus of interest in my career. I'm aware of that now, which doesn't give me a lot of pleasure.

I think people only have so much interest in anybody, and if you barrage them in between the times you have something to offer them you become a personality rather than an actor - much more short-lived. I only work once a year. And that's enough.

I accrued anger from people's low opinion of me and my work, and for the work I might be capable of.
