The movie star spent much of the film in a makeshift coffin, and still can't believe he signed up for the project - because he even freaks out in elevators.

He tells WENN, "I've always had a bit of an issue with claustrophobia, but every time I've read a script that evolves some aspect of that I'm pretty intrigued.

"Buried was life altering for me. I had safe words for that but what's funny is we shot in Barcelona and I was the only one who spoke English, so I remember yelling out a couple of safe words and everyone just looked at me like I was demanding lunch!"
