Trailer (promotion) - Definition

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, an event that does not occur in the final film.
