The History of Film Trailers

A trailer or preview is an advertisement or a commercial for a feature film that will be exhibited in the future at a cinema. The term "trailer" comes from their having originally been shown at the end of a feature film screening. That practice did not last long, because patrons tended to leave the theater after the films ended, but the name has stuck. Trailers are now shown before the film (or the A movie in a double feature) begins.

Movie trailers have now become popular on DVDs and Blu-ray Discs, as well as on the Internet and mobile devices. Of some ten billion videos watched online annually, film trailers rank third, after news and user-created video.

History

The first trailer shown in a U.S. film theater was in November 1913, when Nils Granlund, the advertising manager for the Marcus Loew theatre chain, produced a short promotional film for the musical The Pleasure Seekers, opening at the Winter Garden Theatre on Broadway. Loew adopted the practice, which was reported in a wire service story carried by the Lincon Nebraska Daily Star, describing it as "an entirely new and unique stunt", and that "moving pictures of the rehearsals and other incidents connected with the production will be sent out in advance of the show, to be presented to the Loew’s picture houses and will take the place of much of the bill board advertising". Granlund was also first to introduce trailer material for an upcoming motion picture, using a slide technique to promote an upcoming film featuring Charlie Chaplin at Loew's Seventh Avenue Theatre in Harlem in 1914.

Up until the late 1950s, trailers were mostly created by National Screen Service and consisted of various key scenes from the film being advertised, often augmented with large, descriptive text describing the story, and an underscore generally pulled from studio music libraries. Most trailers had some form of narration and those that did featured powerful voices.

in the early 1960s, the face of motion picture trailers changed. Text-less, montage trailers and quick-editing became popular, largely due to the arrival of the "new Hollywood" and techniques that were becoming increasingly popular in television.

In earlier decades of cinema, trailers were only one part of the entertainment which included cartoon shorts and serial adventure episodes. These earlier trailers were much shorter and often consisted of little more than title cards and stock footage. Today, longer, more elaborate trailers and commercial advertisements have replaced other forms of pre-feature entertainment and in major multiplex chains, about the first twenty minutes after the posted show time is devoted to trailers.

Many home videos contain trailers for other movies produced by the same company scheduled to be available shortly after the legal release of the video, so as not to spend money advertising the videos on TV. The VHS tapes would play them at the beginning of the tape and the few VHS tapes which contained previews at the end of the film would remind the viewer to "Stay tuned after the feature for more previews." With DVDs and Blue-rays, trailers can operate as a bonus feature instead of having to watch through the trailers before the movie.

Definition

Trailers consist of a series selected shots from the film being advertised. 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 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. A trailer has to achieve that in less than 2 minutes and 30 seconds, the maximum length allowed by the MPAA. Each studio or distributor is allowed to exceed this time limit once a year, if they feel it is necessary for a particular film

Some trailers use "special shoot" footage, which is material that has been created specifically for advertising purposes and does not appear in the actual film. The most notable film to use this technique was Terminator 2: Judgment Day, whose trailer featured an elaborate special effect scene of a T-800 Terminator being assembled in a factory that was never intended to be in the film itself. 

Dimension Films also shot extra scenes for their 2006 horror remake, Black Christmas - these scenes were used in promotional footage for the film, but are similarly absent from the theatrical release. A trailer for the 2002 blockbuster Spider-Man had an entire action sequence especially constructed that involved escaping bank robbers in a helicopter getting caught in a giant web between the World Trade Center's two towers. However, after the September 11 attacks the studio pulled it from theaters.

One of the most famous "special shoot" trailers is that used for the 1960s thriller Psycho, which featured director Alfred Hitchcock giving viewers a guided tour of the Bates Motel, eventually arriving at the infamous shower. At this point, the soft-s poken Hitchcock suddenly throws the shower curtain back to reveal  Vera Miles with a blood-curdling scream. As the trailer, in fact, was made after completion of the film when Janet Leigh was no longer available for filming, Hitchcock had Miles don a blonde wig for the fleeting sequence. Since the title, "Psycho", instantly covers most of the screen, the switch went unnoticed by audiences for years until freeze-frame analysis clearly revealed that it was Vera Miles and not Janet Leigh in the shower during the trailer.

There are dozens of companies that specialize in the creation of film trailers in Los Angeles and New York. The trailer may be created at agencies (such as The Cimarron Group, MOJO, The Ant Farm, Ben Cain, Aspect Ratio, Flyer Entertainment, Trailer Park, Buddha Jones) while the film itself is being cut together at the studio. Since the edited film does not exist at this point, the trailer editors work from rushes or dailies. Thus, the trailer may contain footage that is not in the final movie, or the trailer editor and the film editor may use different takes of a particular shot. Another common technique is including music on the trailer which does not appear on the movie's soundtrack. This is nearly always a requirement, as trailers and teasers are created long before the composer has even been hired for the film score—sometimes as much as a year ahead of the movie's release date—while composers are usually the last creative people to work on the film.

some trailers that incorporate material not in the film are particularly coveted by collectors, especially trailers for classic films. For example, in a trailer for Casablanca the character Rick Blaine says, "OK, you asked for it!" before shooting Major Strasser; this line of dialogue is not spoken in the final film.
