Insurgent codes and conventions

Conventions of a film opening	Codes used to convey this convention (e.g. technical, symbolic, written)
The Hook!	The hook for me happens when I see the establishing shit showing the city of Chicago in ruins. This tells me that there had been something very serious happened. The slow music and narration that are also in this part help to make the audience understand why the city looks the way it does.
Set the scene (time? Setting?)	In the future. It quickly tells the audience about what the film is about as well as showing images to back this up. It is also clear that it is in the future because we know that this is not how Chicago look now.
Introduce characters	Kate Winslet is the first actor seen. She is the biggest, well known star  in the film. She is the narrator at this point in the film, telling the audience about the situation.
Introduce the genre	The genre is shown through the ruins of the city. The sci-fi feel is clear as soon as things appear on the screen because the first image is made from pixels. The action genre is also shown when it cuts to inner city shots at 40 seconds in.
Credits	The credits appear on the screen in a white font. These are all production credits. these appear at the beginning of the openings and then at the end the title of the film comes on 'INSURGENT'.
