The document discusses conventions used in the author's short film to conform to the thriller genre. The film includes a plot twist at the end where the main character asks "who's body is in the car?", and uses a blue hue throughout to keep the storyline mysterious. It also challenges the genre with a flashback, a technique not often seen in thrillers but fitting to the story. Binary opposites between characters and the killer vs. victim were also used as seen in other thrillers.
