It (titled onscreen as It Chapter One) is a 2017 American supernatural horror film directed by Andy Muschietti and written by Chase Palmer, Cary Fukunaga, and Gary Dauberman. It is the first of a two-part adaptation of the 1986 novel of the same name by Stephen King, primarily covering the first chronological half of the book. It is the first film in the It film series as well as being the second adaptation following Tommy Lee Wallace's 1990 miniseries. Starring Jaeden Lieberher and Bill Skarsgård, the film was produced by New Line Cinema, KatzSmith Productions, Lin Pictures, and Vertigo Entertainment. The film, set in Derry, Maine, tells the story of The Losers' Club (Lieberher, Sophia Lillis, Jack Dylan Grazer, Finn Wolfhard, Wyatt Oleff, Chosen Jacobs, and Jeremy Ray Taylor), a group of seven outcast children who are terrorized by the eponymous being which emerges from the sewer and appears in the form of Pennywise the Dancing Clown (Skarsgård), only to face their own personal demons in the process.

Plot

In October 1988, twelve-year-old Bill Denbrough makes a paper sailboat for Georgie, his six-year-old brother. Georgie sails the boat along the rainy streets of small town Derry, Maine, only to have it fall down a storm drain. As he attempts to retrieve it, Georgie sees a clown in the drain, who introduces himself as "Pennywise the Dancing Clown". Enticing Georgie to come closer, Pennywise bites his arm off and drags him into the sewer.
