Filmmakers Peter Ettedgui and Ian Bonhôte take IndieWire through the emotional creation of their "Super/Man: The Christopher Reeve Story," which brings the real-life superhero back to vivid life.

Christopher Reeve's children Alexandra, Matthew and Will were a united front at the New York premiere of the documentary honoring their late father. See all the red carpet photos

Reeve died at 52 in 2004, just under one decade after his life-changing fall in 1995. His wife Dana, with whom he shared Will, died two years after Reeve passed away. Reeve shared his older two children with ex-partner Gae Exton, who also appears in the new documentary.
