Explain

CAMERA ANGLES/SHOTS
Tracking shots are used to show status within ethnicity groups. The white man walks around a corner at the start and there is a tracking shot of him. This connotes that he is of high status and it is important and interesting to follow him.

There are high angle shots used to show vulnerability. The immigrants are hiding in the store cupboard and the camera is higher up than them. This connotes that they are inferior to the white officer at the door.

MISE EN SCENE
Composition and layout of a scene is used to represent different ethnicities. This is shown in the canteen scene  where there is a pan around the room of all the different ethnic groups sitting seperately. This connotates a barrier between everyone and that different ethnic groups shouldn't and won't mix. (SOUND) Diegitic sound of dialogue is also used to add to the barrier. The people are all talking in different languages. This works to make the viewer feel uncomfortable and as if they don't fit in within these different ethnicities, this is role reversal.
