Title Sequece

Title sequences are used to highlight the key people in the film such as: Stars/produces and directors as well credit them as they are essential to the film as it would not of been made if it weren't for the stars, producers and directors. The title sequence also indicates the genre of the film and sets the tone by using the genre conventions. Such as any of the following: Symbolic codes, colour scheme, technical codes, font styles, editing effects and soundtrack. These conventions help the audience distinguish the genre. Depending on the style of the film, some films will rather tell the story from present tense and some will start with the past leading up to the future to set the scene.   

Blair Witch for example starts by introducing the main characters and them getting ready for their journey. However not all films start by introducing the characters. Depending on the style of film will depend on what the director will do in the opening.

Se7en for example doesn't start by introducing the characters. Se7en starts by introducing the villain which isn't common in most films. The opening features. The opening shows the villain writing in journals and examining x-rays which leads us to believe that he has been conducting experiments. The cutting off the skin on his fingers with a razor alongside the fast flashes of random images is a clear indication of his mental instability.

Fincher for example uses action in openings to grab the viewers attention whereas Saul Bass uses "typography, colour and imagery" in openings. Film openings are described to be the same as "opening the curtain in the theatre" they start the film off and introduce us to the characters and story, however the style in which the opening is presented in depends on the director an what message he is trying to portray.
