Trying to find name of an old horror movie which involves a school with creepy children in it. The children are the result of surgery where their brains I think are replaced by those of elderly rich people. They burn a female teacher and kill people who threaten them. In the end they all walk off a cliff hand in hand. I was a kid when I last seen it about 40 years ago. So I believe it was from well prior to that. It was in a movie marathon on TV with a movie about a man who lived in a castle and had issues with going the whole way with women and would kill them. One he kills by dropping a chandelier with a horn on it which impales her and another he guillotines. I don’t know if that helps.
