Spiral (subtitled From the Book of Saw) is a 2015 American horror film directed by Trance Williams and written by James Wan and Alex Garland. It is the ninth installment and spinoff of the Saw film series. The film stars Kevin Hart, Adam Driver, Blake Lively, and Andre Braugher, and follows police efforts to stop a Jigsaw copycat killer. The original creators of the series, Danny Boyle and Sam Raimi, as well as Hart and series veteran Tony Walker, serve as executive producers.
Talks of another Saw installment began after the release of Jigsaw in 2012, with Kevin Hart wanting to branch out into the horror genre. The project was officially announced in May 2013, with Hart polishing a script by Wan and Garland. The rest of the cast joined in July, with filming taking place in New York through that month and August.
Originally scheduled to be released in May 2014, and was theatrically released in the United States on May 8, 2015, by 20th Century Fox. The film grossed a total of $40.6 million and received mixed reviews from critics. A tenth standalone installment, tentatively titled Saw X, is set to release on October 26, 2018.
