The Last Winter (2006)

The Last Winter (2008) follows a team of environmentalists working for an oil company as the head to the arctic region of Northern Alaska, where they're setting up a drilling base to find an independent source of energy. Unfortunately, one team member suddenly turns up dead (and naked) in the snow, leaving them all to wonder what, exactly, is going on. One dude has a pretty good theory: Nature is more or less revolting against them, and they're all bound to be targets unless they find a hospital ASAP. One thing leads to another, and they're suddenly trapped inside the base, of course. People keep dying, and it turns out that Mother Nature is much more volatile than even they thought. 

There's not room for much nakedness in the froezen wasteland, but Zach Gilford still makes time to walk around with his butt out at the base the team is residing inside. Natural disaster or no natural distaster,  that's something we'd like to see!
