“A trailer (also known as a preview or attraction video) is a commercial advertisement, originally for a feature film that is going to be exhibited in the future at a movie theater/cinema. It is a product of creative and technical work…Trailers consist of a series of selected shots from the film being advertised. Since the purpose of [this advertisement] 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 but in abbreviated form and usually without producing spoilers. For this purpose the scenes are not necessarily in the order in which they appear in the film. [This type of ad] has to achieve that in less than 2 minutes and 30 seconds, the maximum length allowed by the MPA. Each studio or distributor is allowed to exceed this time limit once a year, if they feel it is necessary for a particular film.”
