Music box?
Did this movie feature a music box or some other device that played a famous piece of music?
There are 3 70s horror movies that scared the crap out of me as a child and I have had a difficult time trying to identify what they were. I'm almost certain this is one of them--I seem to recall that piece of music turning up more than once but I can't remember the music either (argh!). For some reason the image of Stanwyck stands out in my mind though I had no idea who she was when I was a kid.
I know one of the other movies was "The Legacy" in which a woman was swimming and was magically trapped under the water. The 3rd movie featured a woman in a rural house who was having visions of the Salem witch trials.
Any thoughts?
