Why? Because Fox has always been "the kid." A smart-ass with great hair and a body that looks like it never outgrew Garanimals.

Today, to celebrate this mileston, we've compiled the list of the Top 20 roles of Michael J. Fox in film and televsion. Why both? Because Fox has balanced between two two mediums better than any actor of the '80s.
