Now better known for his bad-ass heroics in a series of action films than for starring in the awards-bait dramas he used to churn out on a regular basis, Liam Neeson has transformed himself into one of the more unlikely Hollywood action heroes in recent memory. His latest testosterone-heavy big-screen venture is of course "The Grey", which sees the actor starring as an oil driller who is forced to square off with a pack of snarling wolves after the plane he and several of his co-workers are riding in crash-lands in the remote wilderness. The film is a dream come true for those who enjoy a good cinematic yarn about men going toe-to-toe with Mother Nature, though of course it's only the latest in a long line of films to deal with the subject. In anticipation of the film's impending release, then, we take a look back at ten of the most exceptional examples of the "Man vs. Wilderness" sub-genre - a category made up of films that center on individuals who unwittingly (or sometimes wittingly) find themselves at the mercy of the natural world.
