Actors will go through quite a bit of trouble to get into the character of a film or to simply get that one challenging shot. In Leonardo Di Caprio's case this meant working in -30C temperatures, wading through icy rivers and wrestling with bears.

In an interview with Wired magazine for its January 2016 issue, the Titanic star mentions the endurance required to complete The Revenant based on a real life story. "Every single day of this movie was difficult. It was the most difficult film I've ever done. You'll see, when you see the film — the endurance that we all had to have is very much up on the screen."

For him, one of the worst parts was "getting in and out of frozen rivers" for takes. "Because I had elk skin on and a bear fur that weighed about 100 pounds when it got wet. And every day it was a challenge not to get hypothermia."

A large-scale dryer was used to keep the actor warm between shots because his fingers and toes kept getting locked up due to the cold. "So they were basically blasting me with an octopus hair dryer after every single take for nine months," he explained.

The Wolf of Wall Street actor has had a number of near-death experiences, the most recent being a shark attack. "A great white jumped into my cage when I was diving in South Africa. Half its body was in the cage, and it was snapping at me. The great white took about five or six snaps an arm's length away from my head. The guys there said that has never happened in the 30 years they'd been doing it."

Previously the 41-year old actor's chute got tangled while tandem sky diving. His co-diver managed to untangle the second chute but they were unable to reduce the speed at which they were falling by much. "The fun part was when he said, 'You're probably going to break your legs on the way down, because we're going too fast now'," Di Caprio recollects.

"My friends have named me the person they least want to do extreme adventures with, because I always seem to be very close to being part of a disaster. If a cat has nine lives, I think I've used a few."

When plane engine blew up

Jinxed? The Django Unchained star also happened to be on a Delta Airlines flight to Russia when the engine blew up. "I was in business class, and an engine blew up in front of my eyes. I was sitting there looking out at the wing, and the entire wing exploded in a fireball. I was the only one looking out at the moment this giant turbine exploded like a comet. It was crazy. They shut all the engines off for a couple of minutes, so you're just sitting there gliding with absolutely no sound, and nobody in the plane was saying anything. It was a surreal experience. They started the engines back up, and we did an emergency landing at JFK."
