I remember a movie from the 70s/80s. At some point, the hero is supposed to marry a girl. Before they marry she reveals to him that by day she is a woman but at night she is a pig. She asks him to choose if he would rather have her be a pig during the day or a pig at night.

The hero states he cannot make the decision for her. She must make it for herself. With that, the curse is broken and she remains a woman full-time. I wish I could remember other parts of the film or the characters names but I cannot.

It is not animated. It is not Penelope. For some reason, I keep seeing the guy from the original Clash of the Titans (Harry Hamlin) but I don't think it is him. Does anyone know what movie this is?
