I'm not a political animal, I'm a curious animal.

What triggered a migraine for me may have no effect on someone else. For many people, coffee can relieve symptoms somewhat, but for me it was a trigger. You really have to find out what affects you individually.

Hiding my migraines on the set may have been my toughest challenge as an actor. There were times when the pain from migraine headaches was so severe that I literally had to crawl across my dressing room floor. But I couldn't let anyone know. If they thought I might slow production, I figured that would end my career.

Saving the world via medical research or going off to Gobi Desert to dust off dinosaur eggs is what I thought I might be doing when I was a kid, and I'd love to bring those interests to a show like 'E.R.' or 'The West Wing,' or a movie like 'Jurassic Park.'

I have a lot of stands on a lot of political issues. I'm very big on campaign finance reform. I still think most Americans aren't aware of how the dumping of big corporate dollars and private donor dollars has totally corrupted the political system and taken it away from them.
