Liam Neeson recently sat down with ET to talk about his newest film The Grey, which is centered upon a team of oil drillers who struggle to survive the harsh conditions of the wild after they are stranded by a plane crash.
While Neeson was reeled in by the attractive script, he admitted, "I thought, 'It's going to be impossible to shoot this,' but I was intrigued."
Although he enjoyed being a part of the project, Neeson divulged that the filming conditions were rather harsh.
"It was terrifying," he confessed. "I'll be really honest. The first week was very, very scary. We were in minus 40 degrees…I remember thinking, 'We're never going to finish this film. It's just going to be physically impossible because all you think about is trying to stay warm.'"
