TEASER TRAILERS : .....

A teaser trailer is a short version of a movie trailer which is designed to pique the interest of the audience, getting them excited about an upcoming film. Teasers, as they are called, are typically released months in advance, sometimes as much as 18 months before the expected release date of the film, and they are used to build anticipation and curiosity about the films they advertise. Teaser trailers can be seen before feature films in some movie theaters, and they are also released online and shown on television.

Classically, a teaser trailer lasts between half a minute to a minute. It may include footage from the film, often in a rough stage, since the film has not been completed, or it may utilize entirely new source material. In some cases, a teaser trailer is simply an abridged version of a regular movie trailer, including the film's tagline and key footage in a condensed version which is more television-friendly.

Some companies like to make teasers which literally tease their audiences with puzzles and cryptic references. For example, a teaser trailer might flash a few key images, followed by a title card with the date. Viewers are supposed to recognize the images, and infer that the date is the projected release date. This works best for iconic films and films in a series, as viewers become familiar with specific symbols. A classic example of this type of teaser trailer would be a promotion of a Batman filmwhich flashed the famous Batman symbol on the screen, followed by a date.

Teaser trailers may also include hints and clues which viewers can follow, if they feel so inclined. It is becoming increasingly popular to include web addresses in teaser trailers, so that viewers can go look up the film online, and some movies had used these addresses as a jumping-off point to involve viewers in an alternate reality game or series of puzzles, thereby drawing them into the story of the film. Others offer viewers the opportunity to sign up on a mailing list for news about the film, including notifications when longermovie trailers are released.
