The document discusses potential locations, props, and costumes for a horror film trailer. It examines 6 interior and exterior locations in a family home that could be used for scenes involving the family as well as for the possessed main character. Key props are identified like a pen used to write disturbing messages, a teddy bear belonging to the main character that plays a role in her possession, and a household object later used as a weapon. Costumes are proposed for the main characters - the father dressed formally, the mother looking older, and the young girl appearing girly at first but her clothing deteriorating as the evil spirit takes control.
