Conventions of film openings

Film openings consist:
-The production company
-Distribution company logo
-Setting the scene of the film, (location too)
-Music which is used to set the mood of the film
-Key characters in the film.

An example of this would be the film One Hour Photo.

We first see the distribution company which is by Fox. After the title sequence we see the main character in a close up shot. 

We then see over the shoulder shots when the detective seems to be interrogating the main character. The mood of the scene seem to be intense and serious.
The film is shown backwards, which means that we basically see the ending of the film first, and are taken through what happens during the film.
