The scariest movie I've ever seen was a Japanese movie called Ju-on. Later, Americans remade it and called it "the grudge" if you've heard of it. Well, don't watch it, watch the original Japanese version with english subtitles. Ju-on. Frickin scary.
It's a British film about a group of soldiers on a training mission in a huge isolated forest, things go tragically wrong when they get attacked by a bunch of werewolves.
It's a great film, scary, action packed and funny.
