YouTube has a nice (if nowhere near this crisp) copy of Lady Vampire from 1959. I had never even heard of that. Now I can’t find the channel anymore, though, and apparently it’s been deleted. That’s a real shame, as they had a lot of great Japanese and British horror movies. No licenses though, I’m guessing.
Lady Vampire is interesting because Japan doesn’t have a folklore backgroup on vampires, and so the film flips a lot of the lore in fun ways. It features one of the most useless ‘heroes’ I’ve never seen, and really doesn’t actually have a lady vampire at all. Still worth a look, though.
