The Killer

The Killer is a 2023 American action thriller film directed by David Fincher from a screenplay by Andrew Kevin Walker. It is based on the French graphic novel series The Killer written by Alexis "Matz" Nolent and illustrated by Luc Jacamon. The film stars Michael Fassbender in the main role alongside Arliss Howard, Charles Parnell, Kerry O'Malley, Sala Baker, Sophie Charlotte, and Tilda Swinton in supporting roles. In the film, Fassbender plays an assassin who embarks on an international vendetta after a hit goes wrong.

Development on the graphic novel adaptation began in November 2007, when Fincher was reported to direct the film with Alessandro Camon writing the script, and Paramount Pictures and Plan B Entertainment, respectively, were hired to distribute and produce the film. By February 2021, Fincher moved the project over to Netflix with Walker replacing Camon as writer and Fassbender circling the lead role. Swinton joined the cast that October, with filming beginning the following month, and wrapped March 2022. Filming locations included Paris, Dominican Republic, and several places in the United States.
