Trailers consist of a selection of shots from the film being advertised. The purpose is usually to attract an audience, so many of the selected shots are the most 'exciting' shots.
The MPPA allow 2 minutes and 30 seconds as the maximum length for a trailer, but each distributor or studio can exceed this once a year. They can be either of a theatrical or teaser nature,
Teaser Trailer
- Sometimes released before a theatrical trailer
- Intended to 'tease' the audience and leave them wanting more
- Usually shorter than a theatrical trailer (1 minute 30 seconds)
- Create mystery
- Usually used by big budget films with larger target audience
- Showing too much of the film at this early stage could loose audience interest

Theatrical Trailer
- Generally longer (2 minutes 30 seconds)
- Shown closer to the release date
- Contains more footage from the film
- Provide more insight into the narrative
