The Michael J. Fox Show marks a full-time return to TV for the actor, who left a starring role on Spin City in 2001 as symptoms of his Parkinson's disease worsened. After Spin City, Fox appeared in occasional guest roles on shows including Scrubs, Boston Legal and Curb Your Enthusiasm. Fox got his start on Family Ties before starring in films including Teen Wolf, The Secret of My Success and Doc Hollywood.
Fox told Rolling Stone in September that Parkinson's has made him a better actor. "That hesitation, that Parkinsonian affect, is an opportunity to just pause in a moment and collect as a character and respond to what's happening and just gave me this kind of gravitas," he said as part of a cover story. "It really gave me a new view of things."
