The document discusses conventions used in movie trailers that the author took inspiration from for their own animated comedy trailer project. These include using a school bell at the start to indicate the school setting, introducing characters through animated titles or profiles, and juxtaposing dialogue to form fake conversations for comedic effect. The author analyzed trailers for films like Mean Girls, Angus Thongs and Perfect Snogging, Step Brothers, and Diary of a Wimpy Kid to find techniques to incorporate into their trailer.
