Research: Mise-En-Scene:Setting&Iconography.

Setting and Iconography are important to a thriller because they can create an initial understanding of what will occur, without the audience actually having to see anything yet.

Denotations are the physical presence of something e.g. a knife, and a connotation is what you can interpret from an object e.g. the knife will represent death, and murder.

The setting of a scene can influence the emotion that is drawn from it. For example in a thriller movie, the locations would normally be in a dark, derelict area. This is because they are quite eerie places, so the audience will become more afraid of the events that are happening. This is because no outsiders would be there to help them escape form the antagonist; therefore, they will know that they are probably going to die. 

The setting of a scene is very dependent on the sub-genre of the film, also. For example, a psychological thriller is more likely to be set in a house, because it makes the audience question their safety of their own home. Whereas, an action thriller is more likely to be set in an urban location, because the action of the scenes ties with the busy atmosphere of the location that has been chosen.
