How is identity represented in Dr Who through Mise en scene?

Dr Who immediately comes across as a man who does not belong in that scene; he is wearing makeup, has gelled his hair, is well shaved and has clean cut sideburns and beard. This all contributes to his general look of a well dressed, clean and modern man, as anyone thinks of Dr Who does. Furthermore, he is well dressed; he is wearing a casual suit with shoes, plain trousers, a simple tie and shirt, although he has no dust or dirt on him from the dingy, worn down theatre he is in, but this is not uncommon as that is his attire and image. Also, once he is in the prison, he pulls out his stethoscope – very verisimilitude as although he is a time traveller, he is still a Doctor, and still carries basic equipment with him.
On the other hand, the commanding general in the theatre is quite the opposite of Dr Who, he is dressed in his army clothes; a green vest, a green jacket, dark combat trousers, polished black boots and a dog tag around his neck – he clearly represents a typical army commander. Moreover, he has a slight crew cut, a rough beard and greying hair, possibly as a result of the stress of everyday life. His personality also adds to appearance; a concise man, who irrationally thinks, believing combat to be the best medium of solving disputes. The other soldiers are all similar to the general; the same attire and eager to fight.
In contrast, Catherine Tate is portrayed as a clean, quick thinking, and a well dressed woman. She is wearing large, golden earrings - impractical for her “job” but it adds to her look. Also she has clean, brushed hair, she is wearing makeup – eyeliner, lipstick etc, and is wearing a fairly trendy cardigan. This tells the reader about her role, she clearly, like the doctor, isn’t from the current time or place. Dr Who’s daughter is good looking, she is wearing makeup, although this partly contradicts her part as she recently has popped out of a machine - it is unlikely that in that environment she would have been able to make herself look fabulous after just being “born”, but it’s Doctor Who so anything goes. However, she is wearing army clothes which is verisimilitude as she was “born” in the army base and therefore would have been provided with their clothes.
The Hath, the Alien soldiers are shown to have orangey, loose skin, are about the size of humans, have no hair and have an alien device for their breathing apparatus which has a green liquid in with bubbles constantly rising up and a glass container. This image is a very stereotypical “costume” for aliens, it is clear that they are not humans because of their physical description as well as their unheard of dialect, their futuristic clothing and weapons and their funky, super technology, for example touch screen holograms. In addition, their surrounding colours are very bright and luminescent: common for the “normal” aliens and the way they are depicted in comic books.
Overall, Identity is represented in Dr Who through Mise en scene with the different characters attire, props, makeup and personality. However, it is also illustrated through the positioning of actors; often Dr Who was in a “place of power” he could see things other characters couldn’t, which reflects his role – the main character. This was also shown through the commander, he would appear the highest ranking in the scene, but Dr Who was on a higher platform – metaphorically showing greater presence.
