The Grey is a 2011 American adventure thriller co-written, produced and directed by Joe Carnahan and starring Liam Neeson, Frank Grillo and Dermot Mulroney. It is based on the short story "Ghost Walker" by Ian MacKenzie Jeffers, who also co-wrote the screenplay with Carnahan. The story follows a number of oil-men stranded in Alaska after a plane crash, who are forced to survive using little more than their wits, as a pack of gray wolves stalk them amidst mercilessly cold weather. The film was both a critical and financial success, receiving generally favorable reviews and grossing more than three times its budget at the box office.
