Caitríona Balfe has landed her first movie role since wrapping production on Outlander.

The actor, who will bow out as Claire Fraser in the hit Starz drama's eighth and final season later this year, is teaming up with Tom Hiddleston and Willem Dafoe for a new Apple Original Films feature titled Tenzing.

The upcoming movie will chart the life of Sherpa Tenzing Norgay and his summit of Mount Everest in 1953 with Edmund Hillary.

According to Deadline, Balfe will play Jill Henderson, a friend of Tenzing who helped organise trips up Mount Everest.

It was previously confirmed that Loki star Hiddleston will play Hillary, while Dafoe has been cast as expedition leader Colonel John Hunt. The role of Tenzing himself is yet to be cast.

What to Read Next

An official logline for Tenzing reads: "Tibetan-born Tenzing Norgay, alongside New Zealand mountaineer Edmund Hillary, both outsiders on a British Expedition, defied insurmountable odds to achieve what was once thought impossible, reaching the summit of the world's tallest mountain, Mount Everest.

"After six previous attempts, Tenzing risked everything for one final venture. He had to navigate treacherous politics and perilous weather as he embarked on the most significant climb of his life.

"Through it all, he did so with humour, warmth, and generosity towards his fellow climbers, but also deep reverence and respect for the sacred Mother Goddess of his Mountain, Chomolungma."

Tenzing will be directed by Jennifer Peedom, who previously helmed the award-winning documentaries Solo, Sherpa, Mountain and River.

When the project was first announced last year, Peedom said she'd been "working towards this film my whole career".

"Tom Hiddleston and Willem Dafoe are two of the most generous and talented actors in the business, so pairing them with our brilliant Himalayan cast is going to be electric," she added.

"I have no doubt this film will resonate widely. We all have our own mountains to climb, and this film shows us what human beings are truly capable of."
