I think we all get our own bag of hammers. We all get our own Parkinson's. We all have our own thing. I think that we'll look at it through the filter of that experience, and we'll say, "Yeah, I need to laugh at my stuff, too."

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.

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.

I'm going to marry a Jewish woman because I like the idea of getting up Sunday morning and going to the deli.

I mean, I enjoy my work as an actor. But to make a difference in people's lives through advocacy and through supporting research - that's the kind of privilege that few people will get, and it's certainly bigger than being on TV every Thursday for half an hour.

As much as Parkinson's is about movement, the end stage is being frozen. So the more I let that happen, the more I'm gonna be stuck within that and unable to reverse it.

I don't subscribe to any particular doctrine or ideology. I just think that there's kind of a good and bad, the good being life in its purest, happiest form, and the other being the darker side of existence.
