My movie memories

[DarkenedAuras]

 A movie about a love triangle (?). I remember that a man was held in something like a hospital or he was a captive of a brunette woman with short hair. She was making cut marks on his chest with a surgical knife or something. I thought that was quite creepy! The other woman had a long blond hair and she was looking for the man, but the brunette lied to her that he wasn't there. I think the movie is most probably from the 80's or early 90's. I am not sure about the country of origin. It might be actually from the USA.

^---maybe Misery.  About an obsessed fan of a writer who was outraged he killed off her favorite character, she kept hurting him in order to keep him there to bring the character back somehow...I don't remember much about it, it took place in her house though and I thought there was a point where someone came looking for him but I maybe mistaken.
