In the early 60s I watched Nightmare Theater every Friday night. Two movies have remained in my head.
One is about a woman – I think in a circus? – who maims or kills beautiful girls. The main character is almost killed or disfigured when she is drugged? and then almost steps into a scalding hot shower the evil woman prepares for her. In the end the beautiful bad girl shows that her beauty was just a mask and her face is really scared and ugly so she tries to destroy the beauty of other girls.
the other movie centers around a house where the basement holds a large circular pit with some shining substance in it. I’m thinking I remember it being green but I can’t imagine we had a color tv so I may have just remembered that wrong. I also think the substance came from a meteor or asteroid. The owner of the house was a famous actor – maybe Vincent Price? – and he lured a young woman there. Her boyfriend helps her escape and the house burns down at the end of the movie. I remember seeing the two escaped lovers standing in the dark watching it burn.
