Freud's theory in 'Enemy'

Dennis Vileneuve's 2013 film 'Enemy', starring Jake Gyllenhaal, is seen to portray Freud's theory of the Id, Ego and Superego. At the beginning of the text, we meet Adam Bell, a History Teacher in a Toronto university. Adam is shown as a very timid man, who has trouble holding down meaningful relationships, yet lives with his girlfriend Mary. One of his colleagues recommends a film to Adam, in which he sees his Doppleganger, Anthony Saint Claire, who has played a few minor roles in a couple of movies. Adam stalks Anthony, and manages to track him down to his apartment where he lives with his pregnant wife, Helen. Adam also manages to get his phone number, so they arrange to meet after much trial and error on Adam's behalf. Throughout the text, there are various subtle hints towards the fact that they are the same person, such as a torn photo in Adam's apartment, clearly from a break up, however later we see the same photo in Anthony's apartment, untorn, showing him and his wife.
I believe that in this text, at some points both Adam and Anthony can be seen as the Id or the Superego, although they mainly just portray their respective roles, as initially Adam seems to portray Superego characteristics, such as being timid and having a job where he is in control, as he is a teacher, and control is a major factor to the superego, and he also dresses formally. Anthony, however, is shown to be more reckless, as he rides a motorbike and dresses in leathers for the majority of the film. At one point in the narrative, they decide to trade places, Adam stays in Anthony's apartment with his wife, and Anthony goes on a date with Adam's girlfriend. In this scene, Adam definitely portrays the superego, as he seems grounded in this role, however Anthony portrays the Id as he argues with Mary whilst driving, causing both of their deaths in a car crash. The fact that it is Anthony's idea to trade places for a day shows him as being reckless as he does not think about the consequences of his actions and how their respective partners will react to this situation. Contrarily, however, the fact that Anthony is married and his wife is pregnant seems to adjust which roles they portray, as Adam is essentially a persona created by Anthony in order to cheat on his wife, so it could be argued in this instance that Adam is the Id, however I believe the other factors overweigh this in terms of labelling either of them as the Id/Ego. Also, the fact that the first thing we see in the text is Anthony at a strip club, where he is handed a key. After Anthony's death at the conclusion of the text, Adam essentially becomes the Ego, as his Id persona is dead. He finds the key that Anthony got from the strip club, and tells his wife that he is busy tonight, therefore implying that he is going to the club and therefore embracing some of the characteristics from the Id. The closing shot of the film is Adam walking into the bedroom where his wife is and seeing her as a giant spider, something which has been prominent throughout the film, as spiders play a big role.
In the text, we encounter a few other 'Superego' characters, the most notably Adam's mother. His mother tries to talk Adam out of his beliefs of another man through the simple quotes 'give up on your dream of being an actor' and 'The last thing you need is meeting strange men in hotel rooms, you already have trouble sticking with one woman, don't you?'. In the latter of these quotes, she is clearly talking about his affair on his pregnant wife with Mary, however this subtle hint towards them being the same person could easily be overlooked by a passive audience.
Lighting and framing is vital in this film, as in the scene where Adam and Anthony meet for the first time in the hotel room, Anthony is lit much more low-key than Adam, who is lit quite naturally through the window, which emanates the darkness within Anthony, and perfectly represents him as the Id and Adam as the Superego. The mise-en-scene of each character also perfectly portrays their respective roles, as Anthony dresses mostly in black, with his leather jacket being prominent throughout the text, whilst Adam wears a tweed suit jacket with beige trousers and a white shirt and black tie, which is much lighter than the attire of Anthony, clearly showing him as the Superego. However, in the climax of the film, when Anthony is killed and Adam becomes the Ego, he wears a black suit, a compromise between the suit that Adam wears and the black jacket that Anthony wears, showing that he has embraced some of the darkness within him and also showing that despite all that he has been through in the film he will never change his deceitful and manipulative ways.
Overall, I think 'Enemy' does an effective job of portraying the Id, Ego and Superego, due to the fact that Adam and Anthony fit into their respective roles of the Superego and Id quite comfortably.
