For me a trailer is Trailer consists of a series of selected shots from the film being advertised usually in cinemas or on TV. Since the purpose of the trailer is to attract an audience to the film, these excerpts are usually drawn from the most exciting, funny, or otherwise noteworthy parts of the film these are mostly not com,pleted narrtaive clues and dont spoil the climax. They should therefor leave you on suspense. A trailer has to achieve that in less than two and a half minutes, the maximum length allowed by theaters.
