Momento

The Conventions of Momento are suspense and tension are present as while watching we are waiting for the antagonist to get murdered.  There is a polaroid picture . There are various types of editing in the opening but the most noticeable one is in the visually effective title sequence. There is non diegetic sound present in the form of a classical instrumental and it is used effectively to emphasis the genre and mood of the film. This is aided by the use of mise-en-scene.
