Armie Hammer Ascends From an Underground Cave | Running Wild With Bear Grylls

[music playing]

ARMIE HAMMER: Whew! Yeah. Good to go.

BEAR GRYLLS: OK. Our gear weighs nearly 75 pounds, and it's too heavy to carry up this ladder. So we're going to cache it on the sea floor like Navy SEALs do when they hide their gear until it can be retrieved later. The danger is when we're resurfacing. You've got to make sure you continually breathe out. If we hold our breath as we ascend, the change in pressure is going to expand the air inside your lungs and can cause them to rupture. Right there. Good job, Armie. OK. I'm gonna go first. Go for it. You're good to climb. Good job, you. Good job.

OK. So that's where the last cove-- that's where we're gonna get through. All right. We went in the water, we went down, we swam for a bit. And it got pitch black.

ARMIE HAMMER: I mean, like, scary dark. The next thing you know, we're in a cave. And now we're about to crawl through what looks to be a birth canal. OK, we're good.

ARMIE HAMMER: [groan] It's really-- came to Sardinia for the comfort. All right. Oh. [groan]

BEAR GRYLLS: Good. [inaudible] out. That's how they access these cliffs.

ARMIE HAMMER: Amazing.

BEAR GRYLLS: I've got our clothes and our boots and backpacks and stuff. Let's get geared up. We do a lot of things on these journeys. That was definitely, though, for me was on the edge and is committing, just because one thing goes wrong in a cave like that in the dark, you could-- I mean, you can feel it here, this swell, you know. It goes wrong very fast.

I mean, just have a look down there. It's like a [inaudible]. But we're now into this journey. We're committed. And the only way from here is up.
