It (sometimes released as It: Chapter One) is a 2017 American supernatural horror film adapted from Stephen King’s 1986 novel of the same name. Directed by Andy Muschietti, the picture centers on a group of children in the small Maine town of Derry who confront a malevolent, shape‑shifting entity most commonly manifesting as Pennywise the Dancing Clown. The film combines coming‑of‑age drama with conventional horror devices to explore fear, memory, and group bonds.

Development and production

Development brought together several production companies and distributors; the film was produced by KatzSmith Productions, Lin Pictures and Vertigo Entertainment and distributed by Warner Bros. and New Line Cinema. The filmmakers emphasized a 1980s period setting, practical effects complemented by visual effects, and a tone intended to balance frightening imagery with human drama. The adaptation focuses on the childhood segment of King’s novel and was intended as the first part of a two‑film adaptation of the source material (1986 novel) and the author’s broader themes (Stephen King).

Cast and characters

The antagonist Pennywise is portrayed by Bill Skarsgård. The central ensemble, often referred to as the Losers' Club, includes young actors whose performances were regularly noted in contemporary coverage: principal members of the child cast and several supporting performers who depict local adults and antagonists. Casting choices and Skarsgård’s portrayal received particular attention for their contribution to the film’s unsettling atmosphere.

Themes, style and score

Stylistically, the film mixes character‑driven sequences with genre‑defined set pieces. Themes include the resilience of friendship, the persistence of childhood trauma, and the ways communities respond to recurring violence. Reviews and commentary often highlighted the film’s production design, period detail, and the way it adapts novelistic material for a mainstream horror audience. The musical score and sound design were used to heighten tension and underscore emotional moments.

Release, reception and box office

Upon release the film achieved significant commercial success. It became one of the highest‑grossing films derived from a horror property, with reported worldwide box‑office receipts that placed it above previous modern records; contemporary summaries note a worldwide gross often cited in trade reports (financial summary), surpassing earlier benchmarks such as The Sixth Sense. Critical reaction was mixed to positive, with praise for the cast and atmosphere and some debate over the adaptation choices when compared to earlier screen versions and the full novel.

As the first chapter of a two‑part adaptation, the film led to a sequel continuing the story of the characters as adults. Its commercial and cultural impact contributed to renewed studio interest in adapting genre novels and in projects that blend character drama with mainstream horror elements.
