The 'Neighbors' star is seen chowing down a bug but later spitting in the preview video for the new reality show that has also tapped Channing Tatum and Ben Stiller to appear.
A glimpse at some famous celebrities' experience in the wilderness has been shared in promos for "Running Wild with Bear Grylls". In one of the videos, Zac Efron is seen eating a bug, but later spitting. Judging from the preview, bug is not the only unusual thing that they're going to taste on the show.
Ben Stiller is going to jump out of a helicopter and in another video he is seen rappeling down a cliff and jumping into the ocean. Meanwhile, NFL Hall of Famer Deion Sanders is jumping between two cliffs, or what Bear Grylls calls "a leap of faith."
Also featured in the promos are Tom Arnold and "Today" anchor Tamron Hall. Channing Tatum is additionally tapped to appear on the new NBC reality series. The "22 Jump Street" actor recently shared a selfie taken with Grylls during their adventure.
"Running Wild with Bear Grylls", which has been ordered for six episodes, follows British survivalist Grylls as he takes celebrities into the most remote locations for 48-hour adventures. Each episode will feature a single celebrity.
" '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," said Grylls.
"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."
The show will premiere Monday, July 28 at 8 P.M. on NBC.
