The opening sequence of the film Brotherhood establishes the main characters as either members of gangs dressed in dark clothing associated with crime, or more wealthy individuals dressed formally in suits and listening to pop music. Scenes show the contrast between the two types of characters in terms of their clothing, music, and environments. Violence is depicted through the shooting of a gang member at the end of the opening sequence, creating intrigue for the audience. Cinematography techniques like low-key lighting and shot types are used to convey themes of crime, darkness, and gang violence. The representation of gangs in London portrayed in the opening sequence is quite negative but realistic in depicting the dangers and deaths faced by young people due to gang involvement.
