I can't be smug, because I know that you can lose anything at any point. And I can't be angry, because I haven't lost it.

The way I look at life, and the way I look at the reality of Parkinson's, is that sometimes it's frustrating and sometimes it's funny. I need to look at it that way, and I think other people will look at it that way.

Everything is cause and effect. If you don't move, nothing will move with you, and nothing will move toward you.

Everybody in the world knew I was before I knew who I was.

If you were to rush into this room right now and announce that you had struck a deal - with God, Allah, Buddha, Christ, Krishna, Bill Gates, whomever - in which the ten years since my diagnosis could be magically taken away, traded in for ten more years as the person I was before - I would, without a moment's hesitation, tell you to take a hike.

I'm also very proud to be a part of a trilogy of films that, if they do nothing else, allow people to check their problems at the door, sit down and have a good time.

There are things I've always wanted to do. Things I may not be able to do, but I never really ruled them out - like running a marathon. It's all a matter of timing for me. I suppose I could probably do it if I planned it out right with medication. I don't set a whole lot of goals. It smacks a little bit of will to me, and I find that will is not the way to go for me.
