Narrative theory.

The trailer for Captain America civil war uses many Hollywood techniques as to character types. Applying Propp's character theory, we have a clear hero in Chris Evan's character Captain America - although Rober Downey jr's character Iron Mans is also a major character so doesn't quite fit the role of Propp's Hero. In many ways, he is shown to be the stronger character and it is his quest (to get every hero to sign a hero law) that drives the narrative.

EQUAILIBRIUM

The film's narrative is clearly introduced in the trailer and follows Todorov's theory of equilibrium. The state of balance is the character of Captain America trying to help people but a bomb makes things go wrong.The introduction of Iron Man creates the disequilibrium - along with the request to get heros to sign a law. The new equilibrium is not shown in the trailer - this is critical because even though a standard Hollywood action thriller narrative would suggest that the two heros fight (as it is shown in the trailer) in the end, the audience have to watch the whole film to enjoy this resolution.

ENIGMA AND ACTION CODES

The trailer is full of Barthes' enigma and action codes. These are designed to draw the audience in and encourage them to watch the whole film to resolve their beef. The major enigma codes the audience will consider revolve around whether they resolve their problems and get together when they are needed whether they become friends at the end of the film . However, there are other enigma codes such as what has happened in each character's past to cause their problems - particularly concerning the flashback concering their fights. Although action codes are important in the genre of action thriller there are still plenty of dramatic scenes such as the killing of an father . This suggests there will be moments of drama and tension in the film and the only way to see these resolved and in full is to watch the whole movie.
