What titles are there in an opening sequence?

These are the two company's that are the distributors of the film. The distributors jobs are to obviously distribute it to the public and sell it on to the audience etc.

These are found

 right at the start of films so they are advertised. We see the production company that helped produce and fund the movie and then the picture company that helped edit it together.

Then we are shown some of the names of the actors and actresses that are involved in the film. We commonly tend to find that their names appear in order of appearance or importance. In this case Jodie Foster is the main actress. 

After we are shown the most important actors and actresses we are revealed to the actual title of the film. We know this is the title due to its serif styles font, creating a statement and standing out more.

 After the title of the film is revealed we are then introduced to more of the actors and actresses that worked on the film. The purpose of the two names in one shot could mean that they are possibly in a scene together or have a key connection in some way.

We then see the people who were directly involved in making the film start to be introduced from the least important to the most, the opposite to the actors and actresses. The job of the casting person is to specificaly cast actors and actresses for certain roles, auditioning and contacting their manager to organise specific things.

The role of the costume designer is to simply design and produce the costumes for the actors and actresses to wear as their specific characters.

The role of the person in charge of the music is to choose a specific soundtrack that fits in with the film. Choosing music that would help to build up a certain atmosphere to create an equal outcome on the audience watching.

The role of the film editors are to simply piece together the collection of filmed scenes, using specific and intentional transitions etc, in order to create a specific effect on the audience such as fast cuts to add tension and panic to the piece.

The job of the production designer is to choose and locate locations and set for the scenes to take place in to continue the realism of the scenes.

The use of the director of photography are the people who set up the cameras; where they go, if they look right, is the specific shot and angle right etc. This is to make sure that maximum continuity is continued throughout.

The producers are rarely seen directly on set as these are the people who sometimes fund the production of the film and aren't really involved in the production side but mostly the buisness side.

The writer is obviously the person who wrote the piece. That fact that it states "written by" and not "screenplay by" tells the audience that this is a piece of original work. It's not a recreation, it's his.

The director is seen to be the most important person of whom is involved in the making of the film as they are the person who tell the actors where they need to be positioned so the piece is at a high standard and has clear continuity, points out changes that need to be made, looking over and confirming the cinematography and bringing the script to life.
