This is an old movie, I saw it in a film class. It was black and white, I don’t think it was foreign but I could be mistaken.
A man visits a family at a mansion (may or may not be future in laws).
The only scene I can really remember is he goes into this dungeon like area, sees his fiance/wife lying on a table, it gets weird and he has all this makeup on and makes weird faces and smears his lipstick all over his face. The camera is up close to him.
Then I also remember lots of bats flying past him and it turns out to be the family who are vampires. It was a weird movie haha
