After its publication in 1986, Stephen King's novel It sparked sequels, remakes, parodies and solidified an entire genre: clown horror. Decades later, director Andy Muschietti revitalized King's popular novel, smashing all box office expectations with the release of his 2017 film It. At the time of its release, the movie set the record for the world's highest-grossing horror film. Examining the legacy of the controversial cult novel, the 2017 box office sensation and other incarnations of the demonic clown Pennywise, this collection of never-before-published essays covers the franchise from a variety of perspectives. Topics include examinations of the carnivalesque in both the novel and films, depictions of sexuality and theology in the book, and manifestations of patriarchy and the franchise, among other diverse subjects.
