Chris Hemsworth and Anna Hutchison, "The Cabin in the Woods"
In one scene, Chris Hemsworth is set on having sex with his girlfriend Anna Hutchison in the woods, and if you've ever seen any horror movie, you know that's a recipe for disaster. Weird things have already started happening to this gang of misfit friends while they're on spring break, so splitting up from the group probably isn't a good idea. However, they're being watched the entire time.
