Michael J. Fox is starring in a new television special, entitled Michael J. Fox: Adventures of an Incurable Optimist. Once a teen heartthrob, Fox is now best known for his ongoing battle with Parkinson’s disease. The special, described as a “compelling look at the transformational power of optimism,” features Fox traveling the world to search for reasons and examples of what makes people happy. The special will air at 10 p.m. Thursday, May 7. After long runs on hit TV series such as Family Ties and Spin City and starring roles in successful films such as Back to the Future, Fox announced in 1998 that he had been diagnosed with Parkinson’s disease. He founded The Michael J. Fox Foundation for Parkinson’s Research shortly after.
