What The Actors From Your Favorite Survival Movies Endured For Their Intense Roles

1. Leonardo DiCaprio In 'The Revenant'
Oh, don't act like you didn't know Leo was going to be at the top of this list. We mean, the man ate raw bison liver for his role in the outdoorsy epic The Revenant! Raw. Bison. Liver.

In a 2015 interview with Yahoo, the actor described the intense filming process for The Revenant – the film, mind you, which would eventually snag him an Oscar for Best Actor.

"I can name 30 or 40 sequences that were some of the most difficult things I've ever had to do," said DiCaprio. "Whether it's going in and out of frozen rivers, or sleeping in animal carcasses, or what I ate on set. [I was] enduring freezing cold and possible hypothermia constantly."
