Michael J. Fox will be joining the cast of Shrinking season 3, which will mean a reunion with the creator of his 29-year-old hit sitcom. Fox is a Hollywood legend, having gained fame from massive 1980s projects like Family Ties and Back to the Future. His career carried on into the following decades with more big hits, but it has now been five years since he appeared in a TV show. This makes the news that Fox will appear as a guest star in Shrinking season 3, alongside Harrison Ford and Jason Segel, all the more exciting.
