Donald Kimball from American Psycho questions Ellis on a series of American Psycho-inspired murders, Mitchell Allen from Rules lives next door to and went to college with Ellis (Ellis even recalls his affair with Paul Denton, alluded to in Rules), and Ellis recalls a tempestuous relationship with Blair from Zero. Imperial Bedrooms (2010) establishes the conceit that the Clay depicted in Zero is not the same Clay who narrates Bedrooms. In the world of Imperial Bedrooms, Zero was the close-to-nonfiction work of an author friend of Clay's, and its film adaptation (featuring actors Andrew McCarthy, Jami Gertz and Robert Downey, Jr.) exists within the world of the novel, too.
