This document summarizes the key elements of a possession horror film subgenre. It discusses conventions like priests helping possessed individuals, isolation/entrapment, and strange physical abilities. The proposed film would feature three characters whose hands are shown moving a Ouija board in flashbacks and scenes depicting their possessed states. Inspiration comes from films like The Exorcist, Ouija, and The Devil Inside for their use of possession, Ouija boards, and challenging of conventions. The unique selling point is the scary potential of Ouija boards.
