Domhnall Gleeson has admitted filming The Revenant was miserable.
The 32-year-old stars alongside Leonardo DiCaprio in the hit movie, which has already earned Golden Globe nominations and Oscar nods.
The film is based on the real life story of US fur trapper Hugh Glass, played by Leo, who was left for dead after being attacked by a bear.
Domhnall and co spent six months filming the movie in artic conditions in Canada.

“Of course it was miserable to make. It did get down to minus 30C and I believe it got down to close to minus 40C,” he admitted.
“We were out in the mud, up mountains and through rivers for seven months. It was a really intense experience,” he told The Ian Dempsey Show on Today FM.
But thankfully Domhnall got to take a break when he returned home to star in Enda Walsh’s play The Walworth Farce – where he starred alongside his brother Brian and dad Brendan.
“I did The Walworth Farce in Dublin right in the middle of it where there was two months when filming broke.

“They literally had to stop filming because the camera froze and they weren’t able to get out to where they needed to go safely anymore.”
Meanwhile Domhnall revealed he accidentally cut into Leonardo DiCaprio’s neck while filming a scene where he was stitching up his wounds.
“It went too according to plan. They had built in these amazing bear slashes on his throat, a prosthetic so I could actually sew the flaps of skin together, which is what actually happened.
“They also had fake blood pouring out of the wound, so I had all that to deal with while I was trying to stitch it back up with these old needles.
“At the end of the take, DiCaprio said, ‘Hey dude, you were actually in my neck on that last one’. But he just kept going, which I found very impressive,” he added.
