The film trailer, the teaser trailer

Film trailers are between 2-3 minutes long. They have about 100 cuts in them. They designed to make the audience feel both:
The pleasure of text - the audience recognises familiar conventions and narratives.
Suspense in the audience - by the use of enigma codes. Who is the killer? What happens in the end?

The film trailer itself tends to be structured in the following way: this structure is not 'set in tone' and can be moved around to have greater effect.
1. The distribution company logo
2. The production company logo
3. The narrative establisher - a series of larger sequences which establish the fundamental storyline of the film.
4. The stars of the USP (Uniquw Selling Point) - often stars or directors. Horror movies traditionally don't always use well- known stars because the audience feel more uncomfortable with actors they don't recognise and don't make them feel secure. In the trailer for the horror movie Scream, the director Wes Craven is the USP because he is famous for directing the cult horror film Nightmare on Elm Street.
5. A series of quick, exciting, suspenseful sequences from the film - this is the convincer in that it should create enough suspence to ensure that the audience decide to go and watch the film.
6. Although the trailer will appear the conventions of the genre.
