The document discusses several theories of production used in Katy Perry's music video. It notes that the video borrows stylistically from the 1980s film 'Sixteen Candles', either as homage or pastiche. It also parodies social media sites by featuring a fake website for viewing photos. Additionally, the video references other iconic figures like Rebecca Black and Kenny G through bricolage. The video employs intertextuality through references to Dungeons and Dragons. Finally, one scene breaks the fourth wall through direct eye contact with the audience and shows narcissism as Perry poses to appear attractive.
