Harry Potter is one of the biggest cultural phenomenons in recent history. Like most millennials, I have fond memories of queueing in line at midnight, sweaty-palmed, for the latest book; of dressing up with friends to go to the cinema or having Potter-themed birthday parties, to the acute exasperation of our parents. Controversies aside, it’s a source of treasured memories for many. How shameful, then, that more people don’t know the story of David Holmes. In 2009, David – the stunt double for Daniel Radcliffe, who played Harry in all the films – was rehearsing for the seventh instalment at London’s Pinewood Studios when a stunt went horribly wrong. Holmes was attached to a rig for a ‘jerk back’, that should have sent him flying into a wall. Instead, he hit it far too hard, and broke his neck. These days, he is a wheelchair user, and is determined to tell his story. “I used to fly, man,” Holmes says. “Yeah, not so much anymore.”The resulting HBO/ Sky documentary is probably one of the most moving pieces of television produced this year. Produced in collaboration with Daniel Radcliffe – who is still good friends with Holmes, and who flexed his celebrity muscle to get it greenlit – The Boy Who Lived is a celebration of Holmes’ life, and of the Harry Potter family that rallied around him after his accident.
