Zac Efron - Zac Efron Completes Scary Stunts For Bear Grylls Show
The Paperboy star teamed up with the Brit to take part in his latest series Running Wild with Bear Grylls, and he was filmed carrying out a number of adrenaline-fuelled stunts for the show.
In one scene, Efron and Grylls are seen stripping off their shirts to scale a cliff face in New York's Catskill Mountains, while the actor is also filmed jumping from a plane.
Grylls says of his co-star, "We reached out to him and he kindly said he was a fan of the show and that he was in 120 per cent. He asked for the biggest, baddest adventure and it was an honor to oblige."
Running Wild With Bear Grylls featuring Efron airs in the U.S. on 28 July (14).
