In Leonardo DiCaprio's upcoming epic The Revenant, the five-time Oscar nominee had to commit hard to the physically demanding role -- including growing out a seriously impressive beard.

ET caught up with DiCaprio at the premiere of his new adventure thriller at the TCL Chinese Theatre in Hollywood on Wednesday where the 41-year-old star opened up about what it felt like when it came time to trim down his epic facial hair.

"It was like shaving dreads or something," DiCaprio explained. "I had that beard for a year and a half."

DiCaprio stars in The Revenant as famed, real-life frontiersman and explorer Hugh Glass, who gets viciously mauled by a bear while on an expedition of the uncharted American wilderness in 1823.

Left for dead by the other members of his expedition, Glass struggles to survive the harsh winter weather while healing from the bear attack, and then seeks vengeance on those who abandoned him.

"It was amazing for all of us, as an entire film crew, to go into the wilderness like this, to really go on this epic journey all together, and really tackle the challenges that nature gave us," DiCaprio shared, recounting the film's difficult and monumental production in the mountains of Canada and Argentina.

"It was an unforgettable experience and a big part of my life," DiCaprio added. "I'm just proud that we have a great piece of art to show for it."

The Django Unchained star also revealed that, despite the grueling filming locations, he still got a visit from his mother, Irmelin, who DiCaprio said is "always a great support system."

However, DiCaprio admitted that she didn't have to suffer through the most difficult parts of the shoot.

"She only came for like a week at the good times," DiCaprio said. "We were there for nine months!"

The Revenant, which is already receiving a lot of Oscar buzz, comes out in limited release on Christmas Day, and opens wide Jan. 8. Check out the thrilling trailer below.
