Michael J. Fox (born June 9, 1961) is a Canadian-born actor, made famous by his role as Marty McFly in the Back to the Future trilogy.
Born Michael Andrew Fox in Edmonton, Alberta, Canada, he adopted the J as a homage to character actor Michael J. Pollard. He has written an autobiographical book, called Lucky Man, about his experience of young-onset Parkinson's disease.
Notable roles include the Back to the Future movies, Mars Attacks!, Teen Wolf, and the TV series Family Ties and Spin City.
He is the voice of Stuart Little in the series of movies based on the popular book by E. B. White; Chance in the Homeward Bound series; and Milo Thatch in Atlantis: The Lost Empire.
In 2000, he announced that he would be retiring from the lead role of Spin City after being diagnosed with Parkinson's disease. (A new lead character would be created for Charlie Sheen, who replaced Fox on Spin City.) He has since become a prominent advocate and fundraiser for stem cell research, which he believes may one day help sufferers of Parkison's and other debilitating illnesses.
In 2003, he wrote a pilot for a sitcom series entitled Hench at Home, but the series was not produced beyond the pilot episode.
Fox married actress Tracy Pollan in 1988. He has four children.
