Comparing teaser trailers to theatrical trailers

Teaser trailers are trailers generally shown far ahead of a film's release date to build up hype about the film and may not even show its title. Theatrical or promotional trailers are shown to, as the name suggests, promote the film a little before the film's release and these are the trailers we usually see on T.V.

These are some typical differences between the two:

• Teaser trailers are shorter than theatrical trailers
• Teaser trailers may show scenes not included in the final cut
• A theatrical trailer almost ALWAYS shows the film's title (a '007' film may not need to show a title for example)
• A teaser trailer may not show the film's title to build hype and discussion about the film
• Teaser trailers may include audience interviews after early screenings
