Branding across all media platforms for a film or TV show needs to be consistent in order to effectively reach its target audience. All aspects of the branding, including posters, websites, and social media, should use matching themes, styles, and messaging to convey a coherent message without confusion. Good branding for The Joker movie exemplifies this strategy, with its dark color palette and clown imagery remaining uniform across all marketing channels to clearly identify the film's 15+ age rating and intended viewers.
