Pia Zadora's movie was based on the 1947 novel The Butterfly by James M. Cain.

he also wrote The Postman Always Rings Twice (1938).

 

Pia Zadora sang the theme song and i love it. it's one of my favorites.

i was able to watch the movie as well and i didn't like it. by then i was already of legal age and didn't need any adult consent/supervision.

 

anyone saw the movie, remember the song or read the novel?
