Well, I have a really big fog machine, a three-foot long homemade machete (bladesmithing is another hobby of mine), a gas mask, a really creepy looking raincoat... and me. I stand six and a half feet tall and I'm rather scary looking when the situation calls for it. But, to be honest... I hate those 'run from the killer/creature' movies. I'd like to do something different. Something very simple, but different... I'd probably try to do it more from the antagonist's perspective, but somehow still make him seem scary.
A good example would be the "Halloween" remake directed by Rob Zombie. It was a surprisingly good movie, but once the story shifted away from Michael Myers, I lost interest (I hated Rob's other films, BTW).
Then again, I might just try to do something like 'Evil Dead'-- demonic possession in the middle of nowhere.
Or maybe both.
Any ideas?
