Channing Tatum and Zac Efron are among the stars who have signed on to test their survival skills in a new TV adventure series.
Running Wild with Bear Grylls will track the adventurer and celebrities like Tom Arnold and Ben Stiller as they spend 48 hours in the wilderness, attempting to survive and get back to civilisation.
The six hour-long episodes will debut on the NBC network next month (Jul14).
Grylls says, "Running Wild allows viewers to see inside the hearts and minds of these guests in a very open, honest and vulnerable way, pushing them out of their comfort zones and seeing what they are like in real life when stripped of all the benefits of celebrity.
"Ultimately, this show is about taking these stars on the adventure of a lifetime and being alongside them when they discover something new and empowering about themselves and their world. For me, that is always a privilege."
