Danny Boyle thinks that he would chew his arm off if he found himself in a situation like Aron Rolston.
The filmmaker is back in the director's chair for his first movie since Slumdog Millionaire, 127 Hours, which tells the story of Rolston.
The explorer became trapped in Utah when a boulder fell trapping his arm - he was forced to amputate his damaged in order to escape and survive
Speaking at a press conference at the London Film Festival the Oscar winning filmmaker said: "One of the extraordinary things about the story is when it's told in a superficial way people say 'Ooh, I could never do that'.
"We'd all do it and if you didn't have a knife you'd chew it off, which is an extraordinary thing to say but animals do it all the time.
"When everything is stripped away, yes you would, I think."
The film may not have hit cinemas yet, it did close the London Film Festival last night, but there is already talk that Boyle can repeat his Slumdog Oscar success early next year.
127 Hours is released 7th January.
