The A Funny Thing Happened on the Way to Cure Parkinson’s gala will be hosted by Denis Leary in New York, with an all-star lineup including Mike Birbiglia, Michelle Buteau, Lisa Fischer, Brad Paisley and Sting.

“All I wanted to do was book that McDonalds commercial,” Fox says, looking back on the early days of his career. “I didn’t know I’d be trying to find a cure for Parkinson’s.”

Fox was diagnosed with Parkinson’s in 1991 at the age of 29. Since launching his foundation, they have raised over $1 billion for research.

Over the years, the foundation has helped to develop a number of therapies to help people with Parkinson’s cope with the disease’s side effects.

“They are therapies that have made life a lot better for a lot of people,” Fox explains. “I enjoy life more. I’m more comfortable in my skin than I was 20 years ago. I can sit down and be calm. I couldn’t do that 25 years ago. That’s the medications, the drug cocktails and therapies that we’ve been a part of.”

At the same time, though Fox is committed to finding more than just effective therapies. He wants to find a cure.

“I just want to get this done,” the actor, now 60, says. “I’m committed to this. I won’t stop until it happens.”
