The document summarizes generic conventions of mise en scene in psychological horror film trailers. It discusses how the trailers typically feature settings in large, isolated houses that make it difficult for victims to escape. Props are used to raise tension and foreshadow violent events, while costumes and lighting aim to present villains as normal at first but increasingly disturbing. Facial expressions start calm for villains but become angry or smiling as their evil nature is revealed, while victims shift from happy to anxious and scared.
