Trailers tell the story of a film in a highly condensed fashion to have maximum appeal. In the decades since film marketing has become a large industry, trailers have become highly polished pieces of advertising, able to present even poor movies in an attractive light. Some of the elements common to many trailers are listed below. Trailers are typically made up of scenes from the film they are promoting, but sometimes contain
deleted scenes from the film. The key ambition in trailer-making is to impart an intriguing story that gets film audiences emotionally involved. Most trailers have a
three-act structure similar to a feature-length film. They start with a beginning (act 1) that lays out the premise of the story. The middle (act 2) drives the story further and usually ends with a dramatic climax. Act 3 usually features a strong piece of "signature music" (either a recognizable song or a powerful, sweeping orchestral piece). This last act often consists of a visual montage of powerful and emotional moments of the film and may also contain a cast run if there are noteworthy stars that could help sell the movie. ''
Voice-over narration is sometimes used to briefly set up the premise of the film and provide explanation when necessary, although this practice has declined in the years after the passing of voice-over artist
Don LaFontaine. Since the trailer is a highly condensed format, voice-over is a useful tool to enhance the audience's understanding of the plot. Hollywood trailers of the classic film era were renowned for clichés such as "Colossal!", "Stupendous!", etc. Some trailers have used voice over clichés for satirical effect. This can be seen in trailers for films such as Jerry Seinfeld's
Comedian and
Tenacious D in The Pick of Destiny. Music helps set the
tone and mood of the trailer. Usually the music used in the trailer is not from the film itself (the
film score may not have been composed yet). The music used in the trailer may be: • Music from the score of other movies. • Popular or well-known music, often chosen for its tone, appropriateness of a lyric or lack thereof, or recognizability. The most often used of these is
O Fortuna from
Carmina Burana by Carl Orff, as well as the works of
E.S. Posthumus and
Beethoven. Popular music may be selected for its tone (i.e. hard rock for an action film, lighter pop for a romantic comedy), or to establish context (e.g. the trailer for a film set in the 1940s might use big band swing). • "Library" music previously composed specifically to be used in advertising by an independent composer. There are many trailer music library companies which produce
trailer music, some of the best known are
audiomachine,
Two Steps From Hell,
Immediate Music and
X-Ray Dog or
SFX and Music libraries like the ones from Moss Landing,
Gerrit Kinkel Productions or RedCola Music. • Specially composed music. One of the most famous Hollywood trailer music composers, credited with creating the musical voice of contemporary trailers, is
John Beal, who began scoring trailers in the 1970s and, in the course of a thirty-year career, created original music for over 2,000 film trailer projects, including 40 of the top-grossing films of all time, such as
Star Wars,
Forrest Gump,
Titanic,
Aladdin,
Braveheart,
Ghost,
The Last Samurai and
The Matrix. He is considered by the New York Times as the pioneer of original scores for film trailer music, A
cast run is a list of the
stars that appear in the movie. If the
director or
producer is well-known or has made other popular movies, they often warrant a mention as well. Most trailers conclude with a
billing block, which is a list of the principal
cast and
crew. It is the same list that appears on posters and print publicity materials, and also usually appears on-screen at the beginning (or end) of the movie. Studio
production logos are usually featured near the beginning of the trailer. Until the late 1970s, they were put only at the end of the trailer or not used at all; however,
Paramount Pictures was the first studio to use its actual studio logo at the beginning of its trailers in the 1940s. Often there will be logos for both the
production company and
distributor of the film. Many trailers are
mixed in Dolby Digital or any other multichannel sound mix. Scenes including sound effects and music that are enhanced by stereophonic sound are therefore the focus point of many modern trailers. Trailers preceding feature films are generally presented in the same format as the feature, being either 35 mm film or a digital format. High bandwidth internet connections allow for trailers to be distributed online at any resolution. Since the advent of
Digital 3D, it has become common for a 3D feature film to be preceded by one or more trailers that are also presented in 3D. One relatively recent trend is the incorporation of so called "bumpers", which are very short fast-paced edits placed at the beginning of a trailer to provide a small tease of what will be shown. Following the spike of short videos across social media, bumpers are intended to quickly grab viewers' attention so that they are encouraged to watch the entire trailer to the end. == Collections ==
