Hi Everyone, please help me out with this. I was born in 63 and remember seeing an old black and white film about a woman who wore a choker necklace and told her new husband it could never come off. It drove her husband nuts and when he finally took it off, her head fell off. For the life of me, I don't remember the name and would like to show my adult children the movie. Please help! Thanks

This is so weird... my older cousin used to tell us this story at night, outside to scare us little girl cousins... had no idea it was a movie, I will try find the name of the film for you!

Scary Stories to Tell in the Dark by Alvin Schwartz
Seems this is the book of short stories that your movie may be based on!
