I am trying to think of a scary movie made in either the late '70s or early '80s. All I can remember is there is a young beautiful lady who is cursed and even though she looks young in the mirror, there is a painting of her down the hall that keeps aging. Eventually, she turns into this old lady in a black dress and dies. I remember she is blonde and I remember the house is old and there's a long hall and a big room with the painting in it. It scared me so much when I was little. It's not Dorian Gray because it's a lady.
Can anyone help? I've looked all over!
