Regrettably I haven't seen the the 70s Bofy Snatchers, though I've heard nothing but good things about it. I LOVED Cabin in the Woods!
Haha! Jason X. Haven't seen Sunshine. Will have to check that one out.
Lektu: Thanks for the info. As much as I love Carpenter's The Thing, I was embarrassingly unaware it was adapted from a prose source. I'll pick that novella up. The Terminator is a close one too, but I tend to categorize that one as action-sci-fi. Sure, it's bloody and the idea of this unstoppable cyborg is pretty terrifying, but the film overall bears the pacing and intensity of a thriller (which, in my view, is not the same as horror). Same with Predator, another one that is definitely sci-fi, and skirts into horror territory, but is most definitely action.
Emmett: Yeah, Hardware is fantastic. I'm glad it's had a proper DVD release. Digital copies transferred from full-screen VHS copies were no fun. auspex: Glad I could turn you on to some awesome movies!
