The document discusses various narrative structures that are commonly seen in teen drama films and their trailers. It analyzes examples like The Maze Runner, Angus, Thongs and Perfect Snogging, and The Perfect Man. The most likely structures for a teen drama teaser trailer are an open ending to avoid spoilers, a non-linear presentation of clips from the film similar to a montage, and focusing on a single storyline of one or two main characters and their realistic issues. Flashbacks may also be used to build romance or intrigue audiences without a clear chronological order.
