Narrative Structure
Most Mystery films follow a common structure. The Hero is going about their day to day life. Then a crime is committed or someone is found dead. The hero either hears about the crime or is approached by a source and sets off to solve the mystery. The hero will then go out of his/her way to catch the criminal. A few more people then die as the film progresses. The villain normally makes slight mistakes that the Hero picks up on. The criminal is always caught.
Cinematography
Close up shots are used to show peoples fear when they discover a dead body or their anger when their most prized possession has been stolen.
High and low angles to either show a potential murder victim as vulnerable and weak or to show the killer as strong and in control.
Setting
They can be set in countryside towns with a low population and miles away from a city.
Good settings for mystery films can be: police stations, big cities forests, city streets, forensic labs, hospitals, docks, lakes, fields.
Sound
Fast paced music is used when the Hero is chasing a suspect. This creates tension as the audience doesn't know if he will get away or not.
