Appearing on "The Late Show With David Letterman" on June 27, actor Channing Tatum shared details on an intense 10-day excursion he took into the Guyana rain forest. 


The "Magic Mike" star says he gathered up 10 of his best friends, consulted with survival expert Bear Grylls, and then took off into the rain forest with two Indians to see "how long we could last."


"It really truly makes you understand how much you really don't need on a daily basis," he told Letterman. "We had a hatchet and a hammock, we were sleeping in trees ... We had MRE's (Meals Ready to Eat) ... but mainly (we) fished ... We just wanted to get away, we felt like if the world ever comes to an end, we would not know what to do in the wild."


While Tatum says the group was as safe as they could be "when there are things that could kill you everywhere," it certainly wasn't a relaxing excursion.


"The biggest threat was actually falling trees ... but more scary was knowing that a snake could be curled up under your hammock, like, when you get up to go pee in the middle of the night... We thought we saw an anaconda, but it just went under (the brush)... This was right after we just saw a picture that the guy had showed us — they cut open an anaconda and there was a person inside of it. There was an Indian inside the actual anaconda."


As for quiet evenings, the 32-year-old says the rain forest was one of the loudest places he's ever visited. 


"You can't actually see the sky because it's a triple canopy rain forest," he says. "And you think it's gonna be quiet and beautiful because you're so far out in the middle of nowhere, but it's the loudest place, it's actually louder than New York City."
