The Dark Knight

Use of colour
In this clip you can see that the use of colour is very bland; the way that the film has chosen to set the events in bleak coloured places sets the tone for the film. If the background of the prison cell for example was brightly coloured, it would not fit in with what was happening in the film; as The Dark Knight is quite a dark film the colours match to the theme. The characters, disreguarding the Joker, are all dressed in blacks and whites which are very plain colours. This could be so as not to distract from the film or it could also be to emphasize the situation that is happenig. The black and white colours also fit subtly support the theme of "good vs evil" white generally being associated with good and black generally being assosiated with bad.
The Joker is however, dressed in brightly coloured makeup; this makes him stand out against the other characters but not in the same way that the use of colour makes the characters stand out in children's films. Instead it highlights his psychotic ways and almost makes him seem less appealing as a person. Although the Joker is put in bright colours, they are also bleak which conforms with the bleak feel of the film.

Lighting
The lighting in the film is very dim, much like the colours. In this clip, though unnoticable unless particuarly looking for it, the light is actually spot-lighting the two characters, having them stand directly beneath the lights it makes them stand out without lighting the whole room irredescently which could take away from the grim feel.
The lighting in the rest of the prison is very dark which could be to emphasize that it is filled with bad people. It also makes the situation almost feel more deperate as a result of the lack of light.

Establishing shot
The establishing shot of the Joker and the policeman in the interigation room shows you the Joker sitting slouched on the floor; this supports his posona of not caring what happens to him. The man standing guarding the door is higher up in the shot than the Joker is which tricks the audience into thinking that the policeman is in charge of the situation. The mise-en-scene shows the room that the two are in to be very bleak and unfriendly which gives a cold feel to the audience.

Dilect
The way that the Joker is manipulating the conversation shows the audience that he is actually in control of the situation although he is lower down and the things that he is discribing such as the way he murders people is extremely disturbing. It is also very creepy how the Joker appears to be so calm as he is discribing terrible things to this man, the way that he says "I want my phone call" as if he has someone he wants to help him is almost creepily humorous because the audience is aware that he is a psychopath and so obviously is plannig something.

Close ups
The close up of the Joker's face whilst he is sitting on the floor is to show the audience how he is reacting to what is being said to him, it adds to how disturbing a character he is because you can see the excruciating detail of his psychoticness when he does things such as sticks his tongue out and traces over his scar with it. The close ups of the policeman show how serious he is and helps the audience to feel compassion for him.

Sound
At the beginning of the clip the music is very quiet and becomes progressively quicker and louder which lets the audience know that the scene is building up to something. The music adds to the tense atmosphere as if everything is becoming bigger and more powerful. Nearing the end of the Joker's and the Policeman's conversation the music dulls down again which makes it seem as if the exciting part may be coming to an end, only to become even louder again. This shows all the differnt twists to the plot and reminds the audience that they will not know what will happen next.
