The account of Fox's public life, full of nostalgic thrills and cinematic gloss, will unspool alongside his never-before-seen private journey, including the years that followed his diagnosis, at 29, with Parkinson's disease.

Poignant and profound, this documentary explores what happens when an incurable optimist confronts an incurable disease.

With a mix of adventure and romance, comedy and drama, watching the film will feel like... well, like a Michael J. Fox movie.
