- Mise-en-scene: Grim settings, aided by low-key lighting, are repeatedly used throughout the film to re-inforce the theme of a dystopian society. Cuaron pays close attention to the costumes worn by actors as they are an essential tool in portraying the 2027 setting without alienating the film's audience [Cuaron stated the film was very much "anti-Blade Runner"].
- Single Shot Sequences: Several lengthy single shot sequences are filmed in a tracking shot/cinema verite style. The audience are made to feel as if they are watching a documentary, and this in turn provides the film with a sense of hybridity when looking at genre.
- Auteur Theory: Cuaron's input is clearly visible to the audience, especially during the single shot sequences. His contribution provides reasons for the film's hybrid nature and decision to downplay the possible science-fiction elements of a 2027 setting.
- Patriarchy: Despite his ruggid appearance and average profession, Theo [Clive Owen] is assigned the role of protecting a young female. This demonstrates the female reliance on a man for her own safety in a time of crisis.
- Anti-Government: The situation of the 2027 setting is built around what seems to be the government's failiure to deal with contemporary issues such as immigration, pollution and terrorism. Whilst Cuaron may not be anti-government at all, he provides a horrific vision of the possible consequences which may arrise if these issues are not dealt with.
- Science-Fiction: Children Of Men incorporates two of arguably the most distinct and common elements of the genre; A futuristic setting and a dystopian society. Other recurring themes are discussed in detail by Neale and Altman.
- Hybrid-genre: Cuaron rejects many other common elements of science-fiction such as artificial intelligence and advancements in technology. As Covert states; 'In most sci-fi epics, special effects substitute for the story. Here they seamlessly advance it'. Cuaron instead concentrates more on the cinematography, this in his attempt to create a cinema verite style feel to the film.
- Robert Stam: His theory of the four key problems with generic labels can be applied to many sci-fi epics, but his theory can only partially be applied to Children Of Men due to it's hybrid nature and neglectance of themes such as alien invasions and artifical intelligence.
- Men: Continue to be the dominant figures in society, but to an extent. Theo represents masculinity, bravery and courage. Soldiers and terrorists all seem to be male, a stereotype dating back to the early 20th century. By having this, it can be argued Cuaron is perhaps suggesting the urge for violence in males is what is preventing a seizure to many conflicts across the world.
- Women: Whilst all the government representatives in a positition of power seem to be male, it is interesting to note that females are not portrayed as sex objects. Thus, it is not a necessity to apply Mulvey's theory to the film. Another significant feature is the role of Julian. She represents the modern women; intelligent and independent.
- Refugee Camps: Cuaron seems to draw references between the refugee camps in the film to ones such as the Guantanamo Bay detainment camp, illustrating the harsh nature in how immigrants and captives are treated.
- It is hard to establish a primary audience for the film. It's fast pace combined with the action and the fact that it's set in the future suggests an audience of young adults is being targeted. However, Cuaron's emphasis on comtemporary issues such as immigration and terrorism can also suggest an older target audience is being targeted as it is fast becoming a stereotype that today's younger generation do not follow politics.
- The film is distributed by Universal Pictures, a global company in the field of Hollywood cinema. However, it is interesting they chose to appoint Cuaron to direct the project for two reasons: he is a relative newcomer to the industry and art-house audiences will be familiar with his work.
- Levi Strauss: His theory of good vs. evil [a plot commonly used in many sci-fi films concerned with the theme of dystopian societies] becomes far more complex when looking at Children Of Men. The begninning of the film sees the audience put in a position where they identify with the government, and in turn see the terrorists as evil. However, as the film progresses and the plot unfolds, the audience learn the terrorists in the film are actually fighting for a good cause, and in turn the audience's morals are challenged as they are faced with the decision of deciding whether to identify with the government or the terrorists.
- Anti-Hero: Theo's ruggid appearance, lack of motivation, history as a protestor and shortage of money very much make him an anti-hero. Science-fiction films concerning dystopian societies commonly use confident and well-skilled heroes.
