The Snowman is a 2017 British psychological thriller film directed by Tomas Alfredson and written by Peter Straughan, Hossein Amini, and Søren Sveistrup. The story is based on the 2007 novel of the same name by Jo Nesbø. The film stars Michael Fassbender, Rebecca Ferguson, Charlotte Gainsbourg, Val Kilmer, and J. K. Simmons, and follows inspector Harry Hole as he tracks a serial killer who builds snowmen at his crime scenes. Principal photography began on 18 January 2016 in Norway, before moving to London and Sweden.

The Snowman premiered on 7 October 2017 at the Haifa International Film Festival, and was theatrically released on 14 October 2017 in the United Kingdom and Sweden, and on 20 October 2017 in the United States by Universal Pictures. The film underperformed at the box office, grossing $43.1 million worldwide against a $35 million budget, and was widely panned by critics, who called it "clichéd and uninvolving." Alfredson later attributed many of the film's problems to the film's rushed production schedule.
