The movie poster?
One of the best of all time? I never saw the movie during its theatrical run but that poster with a picture of the Keep burned in my brain and I never forgot it.
Thinking about it, its kind of odd I never saw the movie on TV. Possibly because the movie would have been even more incomprehensible without the exploding corpses and extended sex scenes so it was never cut for tv?
I never saw the movie on Showtime/HBO, ever. Was it on premium tv?
