Sorority House Massacre

Angela O'Neill (Beth) was hired without knowing that her role required nudity and wasn't aware until she received the script. She refused to do the nudity and was told "It's in the script, so you have to do it." She threatened to walk off set and with such a tight shooting schedule, they relented and agreed to let her keep her clothes on. Noticeably, during the "changing clothes montage", she's sitting on the bed, conspicuously out of sight in the shot of her three friends changing clothes and flashing their breasts.

When Bobby escapes from the insane asylum and jumps over the fence the first shot shows that the fence has a line of barbed wire along the top. The next shot there is no barbed wire.
