Structure of a trailer

Normally, a trailer is structured around the most appealing aspect of the film it's advertising without taking the narrative order into consideration. For example, it may include a sequence of clips from different parts of the film to attract to a wide audience.

A basic structure for a normal trailer is as follows;

• Opening: establishes seeting and introduces and character
• Build-up: relationships established/development of characters and their world
• Problem: a dilemma or series of complications: characters faces with an obstacle to overcome.
• Events: a series of events as characters try to overcome obstacles and solve problems, further complications may arise

A more brief outline of a trailer's structure is;

• Beginning: order is established
• Middle: order is disrupted
• End: order is restored

For a teaser trailer, the structure isn't as developed as a theatrical trailer. This is due to the fact that a teaser only lasts from 30-90 seconds, whereas there is more time for a plot develop in a theatrical trailer which lasts up to 2/3 minutes.
