What The Actors From Your Favorite Survival Movies Endured For Their Intense Roles

8. Liam Neeson In 'The Grey'
At a 2012 TimesTalks panel, Liam Neeson revealed he snacked on wolf jerky to prepare for his part in the film The Grey. While Neeson described the jerky as "quite nice," other members of the cast got physically ill from the canine meat.
