A debilitating accident that would have banished a mere mortal to a fortress of solitude instead prompts a popular actor to soar even higher as a crusading hero in Ian Bonhôte and Peter Ettedgui’s Super/Man: The Christopher Reeve Story (A-). Nearly a decade since his passing, remembered through the eyes of those who knew and loved him, this bittersweet biographical documentary presents the Superman movie actor’s highs and lows as he endeavors to stay grounded in the wake of global superstardom, to break the cycle of a fractured family and distant father and to find power and meaning in his life’s work to advance stem cell science. After an equestrian competition tumble leaves him paralyzed from the neck down, the adrenaline junkie actor turns activist and becomes the man of the masses worthy of his mythic status. Flashbacks to his film career are brief and enjoyable, but this chronicle focuses more on the final chapter of Reeve’s life. It’s also a testament to the love of his life with wife Dana in an intimate and moving portrait of resilience. The film’s format is fairly straightforward, yet a strange connective device in which apparent Kryptonite starts growing on the spine of a cosmos-floating disembodied statue of the actor is not all that fetching. Interviews with the mother of two of Reeve’s children and with his trio of offspring plus fellow thespians Glenn Close, Whoopi Goldberg, Jeff Daniels and Susan Sarandon enliven the storytelling. And appearances by Christopher’s college roommate and lifelong friend Robin Williams add to the film’s plaintive portrait of a man with steely resolve. The tale of a man who changed the planet, daily, may also challenge viewers’ superpowers of stoicism.
