went through several rough patches and failed auditions, Fox continued to have a go-getter attitude. "I was sitting around with all these actors, and I remember thinking, ‘Why is this going to work for me and not for them?’" he recalled.
Fox eventually landed his breakout role as Alex P. Keaton in the hit sitcom"Family Ties," and is famously known for his character Marty McFly in"Back to the Future."He was originally advised to pass on the film due to scheduling, but continued to hustle day and night between the two roles. He filmed"Family Ties" in the daytime, then immediately went to work on"Back to the Future," losing countless hours of sleep.
Once"Family Ties" ended after seven seasons, and he was done working on"Back to the Future," Fox booked a few more acting gigs before he was diagnosed with Parkinson’s disease in 1991 at the age of 29. During another recent interview, Fox speculated whether his partying could have led to his Parkinson’s disease.
