The trailer for the upcoming Daniel Radcliffe-produced documentary about his former Harry Potter stunt double has left fans in tears over the touching story. Released by HBO, the documentary looks at Radcliffe’s double for the Harry Potter film adaptations, David Holmes, who was left with a broken neck after a stunt went wrong

Airing on Wednesday, November 15, fans got a taste of what’s to come. In the trailer, clips show David dressed as Harry Potter in behind the scenes footage, practising stunts, and bringing the magic of the stories to the screen.

In the background David can be heard saying: “Being a stuntman is the best job in the world. You’re constantly being tested. Just risking it all. I used to fly. Nothing’s like it, man.”

Viewers get an insight into his gymnastics prowess as a child, which his parents described him as doing “something for the sheer fun of it”. His parents described him as having “no concept of fear”, while Radcliffe said: “Dave just seemed like a cool older brother.

Home videos, photos and shots of interviews show David before and after his accident on set. He said: “You know, I have lots of great friends, and… I’m so lucky. I’ve had such a crazy life. Such highs and such lows. But I was able to find the light in the darkest of places.”

Emotional viewers couldn’t help but show their support for Radcliffe and David, saying it was “great” to see the actor supporting his stunt double. TheSuperTalks wrote: “I’m crying from this trailer, now imagine the whole thing omggg.” Screenwizardz added: “Prepare yourself guys, this is gonna be a tearjerker.”

GlobalObserverX said: “It's great to see Daniel Radcliffe supporting his former stunt double. An inspiring story of resilience and the behind-the-scenes reality of filmmaking.” INVICTOAI commented: “Wow this is looking amazing."

Back in 2014, David spoke to The Mirror about the accident, explaining it occurred while rehearsing a flying scene in January 2009. During the rehearsal, the stuntman was hurled into a wall, breaking his neck, and leaving him paralysed from the chest down.

David told the publication: “I hit the wall and then landed on the crash mat underneath. My stunt coordinator grabbed my hand and said, ‘Squeeze my fingers’. I could move my arm to grab his hand but I couldn’t squeeze his fingers.

"I looked into his eyes and that’s when I realised what happened was major. I remember slipping in and out of consciousness because of the pain levels. I’d broken a bone before, so recognising that weird feeling across my whole body from my fingertips right down to my toes, I knew I had really done some damage.”
