Hollywood stars are backing a charity founded in memory of a Builth Wells cameraman who died while filming a stunt scene in Africa.

Mark Milsome, 54, was killed on November 18 last year during a night shoot of a car stunt for BBC and Netflix thriller Black Earth Rising in Ghana.

Friends and family have launched the Mark Milsome Foundation (MMF), which aims to nurture young film-making talent, to mark the first anniversary of his death.

Movie stars including Robert De Niro, Dame Judy Dench, Johnny Depp, Dame Emma Thompson and Benedict Cumberbatch have backed the cause by wearing the foundation’s t-shirts.

Last week around 3,000 TV and film industry workers wore the t-shirts, including the cast and crew of His Dark Materials, Rocketman and Ironbark.

Chair of the MMF Kirk Jones said: “The film industry is often referred to as a family. The level of support for the Mark Milsome Foundation is an indication of the loss still being felt within that family a year after Mark’s death.”

Production of Black Earth Rising was halted when the veteran cameraman - whose credits included Sherlock, Game of Thrones and Quantum of Solace - died.

Ghanaian police are still investigating Mark’s death.

Mark’s widow Andra, from Hay-on-Wye, called for viewers to boycott Black Earth Rising when it premiered on BBC2 in September - with the opening episode dedicated to Mark - and has now launched civil action.

Rachel Pavey, a specialist international personal injury lawyer at Irwin Mitchell, said: “We are investigating Mark’s tragic death and are representing the family in their civil case.

“His family are naturally devastated and want answers about what happened. We are liaising with legal representatives of the production company that Mark was working for when he was killed.”

The tragedy came against a backdrop of growing concerns about health and safety in the film and TV industries.

The MMF is exploring how to boost understanding of health and safety in the industry and has unveiled a scholarship in collaboration with the Guild Of British Camera Technicians.

A spokesperson for MMF said: “Mark is recognized as someone who supported young talent with his inclusive, generous and nurturing character, and the foundation’s ambitions are inspired by what Mark consistently did for others.”
