I need help with a title of this movie. I saw it on pbs when I was younger. I think it was made in either the 70s or 80s, but the movie is set in the 20s or 30s. The movie was a strange mystery and creepy. There was a handsome guy engaged to a girl, they seemed very happy and in love. He invited her away for the weekend to meet his family. After meeting the family she keeps hearing screams at night. Turns out that he has a big creepy secret about his family, and she ends up finding out what it is. I think he tries to kill her at the end. Anyone knows what this movie night be called? Not sure if the guy was English or not.
