There’s a scene early in the documentary when present-day Michael J. Fox, who famously suffers from Parkinson’s Disease, swaggers along a street and greets a fan, only to stumble at that very moment and have people surround him with concern. Instead of giving into their pity or pretending nothing happened, he cooly tells the fan, “It was so nice meeting you, you knocked me off of my feet!”

This brief moment tells you all you need to know about the ‘80s icon—Fox refuses to be a victim. Still is his brilliant and admirable attempt at telling his well-known story on his own terms. It covers everything from his childhood and early work in Hollywood to his life-changing roles in Family Ties, Teen Wolf, and most memorably, Back to the Future. It also sheds light on Fox’s life as a husband, father, and Parkinson’s sufferer. Director Davis Guggenheim (An Inconvenient Truth) does a genius job of using faceless reenactments and cuts from films and TV shows to accompany Fox’s narration, which pumps the film with a dynamism that matches Fox’s resilient spirit.

Urgent, clever, and exciting, Still is one of the rare celebrity biographies that serves a higher purpose than just recounting a famous person’s life. Anyone who understands the importance of constantly moving and evolving will appreciate this film’s existence.
