Last May, 'Neighbors' co-star Seth Rogen joked that Zac Efron took every opportunity he could to go shirtless for the movie, which undoubtedly was music to the ears of Efron fans everywhere.

Luckily for those fans, they'll be able to see his shirtless body once again in NBC's 'Running Wild with Bear Grylls,' only this time, he will be facing nature's toughest elements as opposed to Rogen's ridicule.

Efron is one of a handful of celebrities -- including Ben Stiller, Channing Tatum and Deion Sanders -- who joined Grylls on adventures into the wild, far away from the luxuries and comforts of Hollywood. Their 48-hour journeys are documented in each episode.

In this clip released by NBC, we see Efron and Grylls overlooking a cliff next to a waterfall, with Grylls suggesting that they lower themselves down using a rope.

"I can't believe how high this is," a nervous Efron observes.

"I got a great way to make us committed to this," Grylls says as he throws their backpacks into the water. 'We started together, we're going to finish together."

Watch Grylls and Efron make the leap in the video above.

'Running Wild with Bear Grylls' premieres Monday, July 28 on NBC.
