I had wanted to comment on the generally low “octane rating” of the films on this list:
When a film mentions chastity belts at all, it is usually in the context of low comedy, medieval sword-and-sorcery fantasy, or science fiction. One searches in vain for any kind of serious drama, set in the present day or recent past, in which a chastity belt plays an essential or significant role in the story.
Seeing Natalie Portman wearing a chastity belt in Your Highness isn’t really a big deal; had she worn one in Black Swan, for example, that would have been a Really Huge Deal.
