Trailers vs. Film openings

Trailers are used in the media to promote and advertise the release of a new and upcoming feature film. Depending on the size of the production company, and the actors involved, it will be advertised on different platforms on different channels.

In every film - obviously - there is an opening. Different techniques are used for effect in these openings, mainly dependent on the genre of the feature. For example, in a horror, the stereotypical attractive blonde female seen to be walking home on her own after a party at midnight, only to be the victim of a serial killer. 

There are copious differences between film trailers and film openings. 

Firstly, in a film opening, the key crew members will be listed. Usually, finishing with the most important individual, such as the director. These titles will appear throughout the opening, usually fading in and out for a duration of approximately 5 seconds. However, in a film trailer, only the very key and most popular personnel in the film are listed. These induce popular actors, directors and producers.
Secondly, the key points of the film will be highlighted in a movie trailer, however in a film opening, this will be very unlikely. Film openings are designed to hook the viewer in but building up interest, using tension or suspense, or quite simply, extravagance.
