Form Research

Form research is the research of what elements are usually featured in an action/adventure film opening.

Flashbacks
A scene where the narrative goes back in time for a couple of minutes and usually to a key event that links back to something further on into the film. It can also set the mood for the rest of the film.
Planning of landscape/establishing shot
This is used to set the scene and inform the audience where and what time the film is being set.
Narrations
An easy and effective way of getting the audience involved in the narrative straight away. The technique is used to give background information on what is happening or who the characters are , giving the audience an insight so the rest of the film makes sense.
Editing
Action scene a fast paced opening to a film attracts the audience straight away and will make them want to carry on watching. As well it automatically shows the genre of the film if included in the opening.
The Chase 
Chase scene Similar to the action scene, also catches the audiences attention. It involves them as they will want to see what happens after the chase.
Production/Distrobuter logos
Production Logos At the start of most films they will always show the production/distribution logos. If the film has a high budget the logo will be adapted to reflect the genre and story line of the film.
Animation
Animation to portray the beginning of the film in a creative way and visibly show the difference between the film itself and the opening sequence. (e.g. Juno.)
Compliations/Montages
Compilation/montage of photographs or clips, for example, Blue Valentine which is a romantic film, shows photographs to portray to the audience the theme and the relationship between the couple.
Narrative
Narrative content this includes the context (where/when/who). As well the pace of the narrative increases as level of engagement increases.
Soundtrack
Soundtrack this is the use of tone, volume, and tempo, which will generically start quiet and slow-paced.

However, I noticed that some directors prefer to have an unconventional opening to portray a sense of mystery or giving the film an artistic edge. E.g. Lack of credits, Lack of establishing shot, Main characters are not introduced.
