Trailers are pieces of creative work, often made up of scenes from the film that they promote. They are produced by dozens of companies who specialize in this genre of advertising. These trailers may include deleted scenes from the movie, music not on the soundtrack, or footage not included in the final cut.
Trailers are usually three-act structures. The first act is the introduction to the film, which usually includes the director’s voiceover and the billing block. Most of the trailer’s content is in a three-channel sound mix, while the last act is often a visual montage of emotional moments.
Often, the trailer will feature voice over narration that explains a brief part of the plot. It can help the audience understand the film’s premise and provide a satirical take on the story. Voice over narration has become less common in recent years, though. Other movie trailers use cliches for humorous effect. For instance, Jerry Seinfeld’s Comedian spoofs the idea of having a narrator telling you about a movie.
Movie trailers have been criticized for their misleading representations of films. Some have claimed that they present a film in a more action-packed or attractive light than it really is. Others have said that they contain material that was not in the film, and were created for artistic reasons. Still others have claimed that the trailers were created in order to create hype for the film.
In addition to the movie itself, the trailer usually features the name of the director, producer, and cast members. This is done to ensure the best impression of the film on the public. A movie may also advertise a minor celebrity as the main cast member.
There is a limit to how much time the trailer may run, according to the National Association of Theatre Owners. The guidelines ask the film distributors to provide the trailers no longer than two minutes. However, some exceptions can be made.
Another reason that the trailer has a limited length is that the trailer is used for advertising a new TV show or a marathon. Many trailers are shown during the closing credits of the TV show or during the beginning of the marathon.
The trailer is normally produced before the feature film is released. Sometimes the trailer is presented in a different format from the film, like digital 3D or 35 mm film.
Film trailers are typically made by agencies while the film is being cut. During this period, different takes of shots are used, and different scenes are highlighted. Various versions of the trailer are distributed online, often with a multichannel sound mix.
The most popular trailers are from classic films. These trailers are coveted by collectors. Because they are not as polished as modern trailers, many collectors buy them as a way to commemorate their favorite films.
Today, trailers have also been used to promote other media. For example, a trailer for a documentary might contain scenes from other films. Similarly, a trailer for a concert might include songs from other musicians.
