Our seventeen-year-old time travelling hero.
Now:
Aside from the Back To The Future trilogy, Michael has worked continuously throughout the years, appearing in movies like The Secret of My Success and Doc Hollywood. As well as guest starring in television shows, and even his own series, Spin City.
Michael also got into voice acting; he voiced Chance in Homeward Bound: The Incredible Journey (and its sequel), the titular character in Stuart Little (and its two sequels), and Milo Thatch in Atlantis: The Lost Empire.
In 1998, Michael went public with the news that he had been diagnosed with Parkinson's disease, and since then has become a highly visible advocate for more research, even setting up the Michael J Fox Foundation, to help fund it.
Today, Michael is currently working on his new NBC sitcom, The Michael J Fox Show, in which he plays a man dealing with the challenges of Parkinson's disease, all while trying to balance his family life and his career as a news anchor.
