Research into the roles of different characters within thrillers

Thrillers usually show good vs evil added with suspense. Normally the identity of the antagonist in known whilst the protagonist will be known later. A typical thriller will be shown from the protagonists point of view which allows the audience to become more involved in the events themselves and therefore closer to the characters as they see how they interact with others in different situations. Furthermore, there will also be a few short clips from the villains point of view allowing the audience to see how the antagonist acts while by themselves or how they used to act through a flashback which allows the audience to gain information on why they have become the evil person. There are often lots of action scenes between characters which keep the audience guessing what will happen next and how the characters interact with each other. The audience never get a sense of the full plot which allows the film to retain its mystery and suspense until nearer the end. Usually at the end of a film, the narrative is revealed and the audience understand why the characters have acted they way they have.

In the opening sequence this means that nothing can be revealed but has to be compact with suspense and mystery. The antagonist who is the evil person should be identified in the opening sequence.
