Mise-En-Scene is addressed differently in short films because it has to be simpler as short films don’t have enough time to go into massive detail. What I mean is that the audience have to understand what certain things represent (Lighting/costume/setting/behaviour of figures) quicker in short films other wise it will be boring and confusing when things can’t be understood properly. So mise-en-scene is more clearly represented in short films because of the lack of running time that they have. For example in ’17 seconds’ they put the main character in a black suit with a gun as a propp to represent the mise-en-scene. 
Genre in short films is addressed also through the use of iconography that is stereotypical of that genre, like the example above these are used to give off the genre quickly. However it is also addressed through the character types that they include. For example in 17 seconds they have a spy who’s the good guy who is represented as kind and thoughtful whereas the villain is a deceitful and murderous character which is stereotypical of the common villain in films. The narrative is also used to address genre in short films. For example in short films based on spys/secret agents, the narrative is based on the good guy getting the bad guy. Narratives in short films are usually basic because there’s not enough running time in them to divulge into detailed narratives.
Furthermore with narrative, it is also addressed through it been based on a massively cut down version of Todorovs theory. Todorovs theory is based on the stages of narrative (Equilibrium, Disruption, Recognition of Disruption, Attempt to repair Disruption and Reinstatement of Equilibrium) However in short films they only really include the disruption, the recognition of disruption and the attempt to repair. Therefore the endings are usually cliff hangers or something of that effect. For example, in ’17 seconds’ the villain kills the spy and in ‘The Elevator’ the main character ends up finding out that he was stuck in a elevator with a bunch of people that had swine flu yet didn’t show what he did about it.
