Liam Neeson didn't think The Grey could finish

Liam Neeson thought the conditions when shooting 'The Grey' were so difficult that the film would never get finished.

Liam Neeson "never" thought 'The Grey' would get finished.

The 'A-Team' actor admits he was intrigued by the project - which tells the tale of a group of men who must struggle to escape the extreme environment in Alaska after their plane crashes - because he was unsure of how it would be shot, and did not think it could be completed after just one day of filming.

He said: "The script read like an epic poem, and it was very tender and very, very beautiful and quite mystical. And was intrigued because I've made 55 films and I thought, 'How the hell is he going to shoot this thing?'

"The first week we were up in British Columbia, it was -40 degrees, and I really thought, after the first day, that we're never gonna finish this film. It was just intense. But we got through it and had a wonderful bunch of actors, and we became very close."

He admits the film was so troublesome that even breathing was "challenging".

Liam added to Buzzinefilm.com: "Walking through snow - doing very very basic things: breathing, speaking in -40-degree temperature - that was the challenge. It wasn't necessarily the character. I knew I could perhaps do that reasonably comfortably. It was just the basic physical things of moving from A to B and saying dialogue. That was the challenge."
