Hello,

I am desperately looking for a drama/mystery/thriller movie. I have seen the last 30 minutes of this movie in the summer of 1991 or 1992 on TV. It was color and made in the 80's or early 90's. I believe it was a period piece (from Victorian era). I remember a saloon of a SEASIDE CASTLE/MANSION and on the main wall there was laying a big painting portraying a misterious woman (her bust); she was moving her eyes (scary!), looking through the dining-room of that mansion, while two men were approaching the painting. There were also other people in the saloon at that time. The woman in the painting had a LARGE WHITE SEASHELL which was covering one of her breasts. Outside it was a big storm (with thunders and lightnings). My father remembers a strong resemblance between the woman in the painting who was dead - she committed suicide jumping from a cliff into the sea - and another woman, who was present in that room. I also believe that one of the female characters in the movie was named Elisabeth, perhaps the woman in the painting. The movie was visually breathtaking: judging by the lavish furniture, the castle/mansion belonged to a wealthy family. It was a US production. I know this isn't too much information, but if you could help me, i would be eternally grateful! Thank you!
