New documentary film Super/Man: The Christopher Reeve Story explores the story of the Superman star's life, and one area it delves into is his close friendship with actor and comedian Robin Williams. Williams features heavily in the documentary, as it explores their friendship since meeting as students at Julliard. In the film, it is revealed that Williams was the first person to make Reeve laugh after the accident which left him paralysed, as he pretended to be a Russian doctor and said he was there to give him a rectal exam.

The film also includes an excerpt from a eulogy given by Williams at Reeve’s funeral. Speaking about why it was so important to include the footage of Williams and the story of their friendship, co-director Ian Bonhôte said: "I think because we ended up making the film so much about family..

. but their friendship was a step above, it was like brotherhood. "They didn't have the same parents, but they were just so tied together.

" Bonhôte continued: "I think when we did the Glenn Close interview, and a few things she said in the interview, it just became clear that we needed to have that arc of Robin Williams stronger than even what we thought early on. "And thanks to, I think, Will and Alexandra and Matt, we got in touch with Marsha Williams, Robin's ex partner, and she was very generous.
