Channing Tatum, Zac Efron and Ben Stiller are among a group of celebrities who will go into the wild with Bear Grylls for his new NBC show.
Running Wild with Bear Grylls will see the survivalist expert take the stars "remote and wild locations in the US and around the world" for 48 hours.
The six-episode series will also feature Tom Arnold, Tamron Hall and Deion Sanders.
Grylls said of his new show: "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."
Running Wild with Bear Grylls begins on July 28 on NBC.
