Hey, maybe you can help me find this movie.
Genre: Dark Comedy (?), probably made 1980-2000.
What I remember: Several people meet in a big house on the countryside for some sort of celebration. However, one woman gets in a fight with her boyfriend which ends in him getting hit over the head with a frying pan (either by the woman or her mother, who was also present). They try to hide the body in the attic.
Then, a thunderstorm starts outside, electricity turns off, and all kind of weird things happen. (If I remember correctly, they also get visited by a church clerk at some point?).
Thank you in advance!
