Michael J. Fox (born June 9, 1961) is a Canadian-American actor, author and voice over artist. His roles include Marty McFly from the Back to the Future trilogy (1985–1990); Alex P. Keaton from Family Ties (1982–1989), for which he won three Emmy Awards and a Golden Globe Award; and Mike Flaherty from Spin City (1996–2000), for which he won an Emmy, three Golden Globes, and two Screen Actors Guild Awards.

Fox was diagnosed with Parkinson's disease in 1991, and disclosed his condition to the public in 1998. Fox semi-retired from acting in 2000 as the symptoms of his disease worsened. He has since become an advocate for research toward finding a cure.

In recent years, he has guest starred on various television shows and appeared as himself in his prime time special Michael J. Fox: Adventures of an Incurable Optimist (A Personal Journey of Hope) in May 2009.
