Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
This one is really bad. Even the snake dancing is boring in this one. It's one of the last films made by Boris Karloff.
Most of the movie is just a woman with Vulcan eyebrows bellydancing with a Boa Constrictor while a midget with glasses and a flower tattooed on his head chooses people to kill. She kills them with the venomous bite of her snake and turns them into Zombies. Later somebody throws a dead snake at a police captain to curse him.
The snakes we see are live Boa Constrictors and gopher snakes, and at the end, an Indigo snake.
