Source Code trailer analysis.

Source Code is an 2011 action thriller movie that was directed by Duncan Jones and released by Summit Entertainment.

According to the uses and gratifications theory, the audience would watch this trailer both to personally identify with the celebrities featured in the film and to gain surveillance- to gain information on what the film is actually about and if they want to go and see it or not.
The trailer starts off with distorted images and close ups of his watch, the train tracks, the woman's mouth and the main characters eyes. It contains very quick editing cuts within the first few seconds, along with a non-diegetic, high pitched sound and a woman saying "hey, Sean?" and her voice also gets distorted. This is used to bring in the whole idea of confusion, to get the audience questioning about what is happening. There is then a long shot of the train to tell us the location; and we then get a close up of the main character to show his emotions and that it's him going through all this confusion;then a medium shot inside the train to show us the woman that is sat in front of him and to introduce her to the scene.
There is non-diegetic sound the whole way through; suddenly getting louder as little, seemingly non-important things happen (such as the boy who opens a can of pop, and the coffee spilled on his shoe.) This reveals to the audience that this isn't right; that something abnormal. We then get a black screen with the font over top "This is not his life" which is purely to provide information for the viewer and to help them understand the situation. To back this point up, we immediately have a close up of the main character as he looks into a mirror, and the camera spins round to show that the reflection is in fact not his.
Within the first 40 seconds, we see the trains collide and the huge explosion engulf the trains. This reveals to us the main storyline of the film, and also suggests that the institution had an extremely high budget to conduct highly realistic special effects such as this.After the explosion, the trailer turns onto the slightly more sci-fi side. It introduces the audience into what the 'Source Code' actually is; using non-diegetic voice overs and sound bridges (such as, at 1:05 we see an extreme long shot of a motorway and the surroundings; and then it jumps to the woman who is explaining about Source Code)
In the trailer; women are presented in different ways. For example; the main female character whom we see at the start is presented as feminine, sensible and perfect. The females whom work on the Source Code project are presented as highly efficient, strong willed and highly intelligent.
