An icon means nothing to me. I don't understand what it means to anybody actually. It seems like a word of convenience. It seems to attend to the huge success of certain kinds of movies that I did, but there's no personal utility in being an icon. I don't know what an icon does, except stand in a corner quietly accepting everyone's attention. I like to work, so there's no utility in being an icon.

My ambition from the very beginning was to make a good part for myself, something differently to what lately I've been doing.

[ Chadwick Boseman] is a remarkable actor, and he's a remarkable person.

I have children. I have other concerns. I have other focuses. I really feel very sympathetic and I would love to be able to help but I don't see this as the opportunity, having done 'Extraordinary measures', for me to suddenly leap on a soap box and begin to talk about the pharmaceutical industry or the desperate plight of sick children. I do what I can in my world but I don't have the bona fides to do that right now.

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.

The environment has become a political, polarizing issue.

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.
