To be associated with a film that just flat-out makes people happy is such a blessing and a tremendous privilege, and I'll always be grateful for it. People's eyes light up when they talk about it. I've been in Asia, Africa, Europe and even Bhutan; people know the movie there. It's just an amazing thing.

Life is good, and there's no reason to think it won't be--right up until the moment when everything explodes into a fireball of tiny, unrecognizable fragments, or it all goes skidding sideways, through the guardrail, over the embankment, and down the mountain. This will happen (and probably more than once).

The moment I understood this - that my Parkinson's was the one thing I wasn't going to change - I started looking at the things I could change, like the way research is funded.

I like to encourage people to realize that any action is a good action if it's proactive and there is positive intent behind it.

Medical science has proven time and again that when the resources are provided, great progress in the treatment, cure, and prevention of disease can occur.

I have no argument with those who see in organized religion a template or an imperative to live life according to a prescribed set of beliefs. Just give others the room, within the laws of civil society, to believe or not believe whatever they like.
