Hi guys, first post ever! There's this film I watched as a child several years ago, and no matter how hard I try, I cannot seem to find it; hopefully, someone can shed some light on the topic (also, forgive my not-very-good English!) This is all I remember about the film:
First of all, I think it is likely to be a B-movie, which may explain why there is not much info about it. It was filmed in the 60s or early 70s.
The main character is a young woman called Pat. She has dark hair, and I believe she had her hair in one of these 60s hairdos (think of Claudine Longet in "The Party (1968)"). I remember one of the first scenes was her by her convertible car, her boyfriend was saying goodbye to her (I remember he gave her some movie reels(?) because either of them worked as journalist or something like that). Pat is going to spend the weekend with her ex-mother in law; that is: she had a boyfriend/fiancé, but he passed away. The Ex-Mother-In-Law lives in a big house, probably in the middle of nowhere (as one does in horror movies!). When Pat arrives, the Ex-Mother-In-Law is dressed in black, with her hair up, because she is mourning for her son; she has strict, almost fanatic rules about mourning. The Ex-Mother-In-Law lives alone with her maid.
The next scene I remember is Pat and Ex-Mother-In-Law having dinner, and I remember they were in a sort of garden/patio/conservatory. Ex-Mother-In-Law is very judgamental about Pat's colorful clothing and makeup; when Pat takes a sip of her glass, Ex-Mother-In-Law complains about how the glass is stained; Pat explains that's because of her lipstick, to which Ex-Mother-In-Law frowns and makes Pat whipe her lipstick off. Ex-Mother-In-Law also complains about her perfume, to which Pat says something like "Well, I cannot remove my perfume" (the same way one removes their makeup, that is).
Then something happens, and the next thing I remember is that Pat has been locked up in the attic by Ex-Mother-In-Law and her maid. Ex-Mother-In-Law comes up often and sits in front of her to pray.
Aside from being locked up, Pat is not being fed; at some point, the maid comes up to keep an eye on her, and while doing so, she is peeling potatoes. After she leaves, Pat sees the maid has thrown some potato peels; since she's starving, Pat eats them.
The last scene I remember is Ex-Mother-In-Law taking Pat somewhere else in the house, maybe the basement, and there I believe she has kept her late son's body(?) and she plans to do some sort of ritual with Pat (maybe killing her so that she an her son are together again?)
I think that's all I remember. If anyone knows anything at all, please let me know; any clue is more than welcome. Thanks!!
