Conventions of an opening sequence

Within the first few seconds of the opening sequence of the strangers there is a black screen with super imposed writing. Shortly after this is shown a non-diegetic voice appears and begins to read out what the super imposed writing says. As the super imposed visual continues the writing changes and gives the viewer a brief description about the year this happened where, but still with a non-diegetic voice over. Just after the first minute of the film has gone the viewer begins to hear a diegetic sound of an engine being turned on and the medium long shot fades in from black and begins to reveal a street with a row of houses. This shot is establishing the location but it is not yet clear where this is. Once again the shot fades out and then back in from black and begins to reveal some more houses. Each shot within this opening sequence is shot with natural light and as the shots carry on it starts to reveal to the viewer that the sun is slowly setting and is slowly becoming dark. This carries on for another 30 seconds and we then begin to hear a diegetic sound of a police scanner. The screen slowly fades to black as we hear a woman crying down the scanner but once again the shot fades in from black revealing a car with a smashed in window and two children standing in between the hole, this appears to be a long shot and this shot is establishing something that has happened. This is now where to film begins to start.
