The document discusses the marketing of a gangster film set in London with a diverse cast. It explains that the poster, magazine, and trailer for the film incorporate consistent iconography, actors, and settings to clearly link them. The film's unique selling points are its London location, which subverts gangster film conventions, and its diverse cast, which is rare for mainstream marketing. For marketing, the poster is in portrait format for various display locations to fully immerse viewers in the narrative.
