In the new Bear Grylls Running Wild trailer (below), Zoolander star Ben Stiller jumps off a rock face, True Lies actor Tom Arnold treks through the jungle, and celebrities open up about their fears and anxieties, while out in the wild.
The six-part show sees Grylls take A-listers into the wilderness for 48-hours each. Channing Tatum, and 17 Again star Zac Efron have also stepped up to the challenge, as has news correspondent Tamron Hall and American sports star Deion Sanders.
Life changing activities during the show are set to include skydiving in the Catskill Mountains, scaling cliffs in Utah and trekking in Scotland.
“Ultimately, this show is about taking these stars on the adventure of a lifetime,” explained Grylls, “and being alongside them when they discover something new and empowering about themselves and their world. For me, that is always a privilege.”
