Intertextuality refers to how one creative work is influenced by another through similar styles, characters, or techniques. This creates a sense of familiarity for audiences by establishing connections between existing works and new versions. Examples include Robbie Williams' music video for "You Know Me" which visually references Alice in Wonderland, and Madonna's "Material Girl" video which replicates the style and clothing of the film Gentlemen Prefer Blondes. The document discusses how intertextuality can show admiration for influential artists while making new works more recognizable. It also notes the video will take inspiration from Tame Impala's dream-like music videos and clever editing styles of artists like Childish Gambino and Miike Snow.
