Chaos Walking is a 2021 American dystopian space western action film directed by Doug Liman from a screenplay by Patrick Ness and Christopher Ford. It is based on the sci-fi trilogy Chaos Walking, adapting its first book, 2008's The Knife of Never Letting Go by Ness. The film stars Daisy Ridley and Tom Holland, along with Mads Mikkelsen, Demián Bichir, Cynthia Erivo, Nick Jonas, and David Oyelowo.
Announced in 2011, the film had undergone several rewrites from a first script draft written by Charlie Kaufman, with Jamie Linden, John Lee Hancock, Gary Spinelli, Lindsey Beer, Christopher Ford and Ness revising the screenplay further. Liman was later announced as the director in 2016, with principal photography fully took place in 2017. Originally set to release on March 1, 2019, it was removed from schedule to accommodate the film's reshoots in April 2019 following poor test screenings with audiences.
Chaos Walking premiered theatrically in South Korea on February 24, 2021, and in the United States the following week on March 5, 2021. It received mixed to negative reviews, with criticism mainly directed to its plot.
