Alex Garland, the screenwriter and director of the film Warfare, discusses the anti-war message of the film while acknowledging that there are circumstances in which war is required. The film tells the story of a failed surveillance mission in Iraq through the memories of war veterans. Garland aims to recreate the experience as faithfully and accurately as possible, and the film has been well-received by veterans who feel heard and understood. The cast of the film, which includes Will Poulter and D'Pharaoh Woon-A-Tai, bonded through a bootcamp and living together during the shoot.
