Still: A Michael J. Fox Movie premiered on Friday at the Sundance Film Festival in Park City, Utah. The documentary, from Oscar winner Davis Guggenheim ( An Inconvenient Truth , 2006 Sundance Film Festival), recounts the remarkable life and career of Michael J. Fox. From his breakout role as Alex P. Keaton on the sitcom Family Ties to Marty McFly in the Back to the Future trilogy, Fox became a superstar in the 80s. But at age 29, Fox was diagnosed with Parkinson's disease. We caught up with everyone involved in the Apple TV+ project at the packed red carpet premiere.
