Pontianak (1975)

A singer catches sight of a woman in the audience. The couple leaves the nightclub in the singer's sports car. When the boy finds a suitable spot to park, he's very surprised to see his companion's dark hair has turned pure white. What's more, her skin has turned grey, and she has enormous pointy fangs sticking out of her mouth. He tries to run away but she catches up to him... meowing and snarling all the while. She leaves his body in the crook of a tree... swingin'...
