Trailers are a type of cargo transport vehicle that can be attached to the back of motor vehicles. They are available in a variety of sizes and configurations, allowing them to carry different types of cargo. They are also very efficient and cost-effective, as they can be used to haul large amounts of weight over long distances at a fraction of the costs of using larger trucks. This makes them very popular among trucking companies and businesses that deal with transporting goods across the country.
Trailers typically feature a condensed version of the film they are promoting and may also contain additional material that is not in the final movie. They usually have a three-act structure and follow the same general pattern as a feature-length film: an opening act that establishes the plot premise, a middle act that drives the story forward, and a closing act with a dramatic climax. The end of the trailer often features a powerful piece of “signature music” (either a recognizable song or a sweeping orchestral score) that adds gravitas to the scene.
One of the most famous examples of a trailer featuring material that is not in the film is Alfred Hitchcock’s Psycho trailer, which featured him giving viewers a guided tour of the Bates Motel shower, culminating with Vera Miles screaming in the shower. This is an example of a “special shoot” trailer, which is footage that was shot specifically for promotional purposes and does not appear in the final film.
A pop-up camper, also known as a collapsible trailer, is a compact recreational trailer that folds down to little more than a height of four feet and is designed to be towed by a medium-sized sedan. A toy hauler is a type of trailer that has a ramp you can fold down to load and unload outdoor “toys,” like motorcycles, ATVs and bicycles.
In addition to the main trailer for a film, there are also a number of other types of trailers that may be included on DVDs or other media releases. These include a montage of key scenes that are not in the film, deleted scenes and alternative camera angles from the main trailer, and featurettes that provide behind-the-scenes information about the making of the movie or TV show.
Another kind of trailer that is sometimes made by fans is a fan trailer, which uses audio or video of the original studio trailer and often incorporates animation techniques to create an independent movie-like film. These trailers are particularly popular for films that have become cult classics. They can be found on YouTube and other websites where fans can share their creations. There are even a few DVDs that exclusively contain trailers for various movies.
