There was a movie that seemed to be above 1990’s - early 2000’s very corny and campy. It seemed have some sort of recreational center and there was a medieval theme long abandoned. There seemed to be some sort of flash back some where though where a man dressed as a knight with good intentions brings a cake for a teenager and the jerk throws it in his face. And later on there seemed to be a high school prom party and he was out to kill teenagers. I remember him bludgeoning one boy on a balcony level. He wore a white mask and seemed to be short and fat! He may have had a daughter that was now a teenager like in so many teenager slasher films but this one was very strange. Any one have any thoughts?
