or may not keep the title "trilogy". The first three novels in The Hitchhiker's Guide to the Galaxy series were dubbed a trilogy, and even after he extended the series, author Douglas Adams continued to use the term for humorous effect - for example, calling Mostly Harmless "the fifth book in the increasingly inaccurately named trilogy." Kevin Smith's films Clerks, Mallrats and Chasing Amy were often marketed as "The New Jersey Trilogy" because they had overlapping characters, events and locations. After the release of a fourth film, Dogma, the series is referred to as "the View Askewniverse". The Star Wars trilogy of three films released between 1977 and 1983 has since been expanded into a trilogy of trilogies: the original trilogy, the prequel trilogy released between 1999 and 2005, and the sequel trilogy released between 2015 and 2019.
