1917 is a 2019 British epic war film directed by Sam Mendes, who co-wrote the screenplay with Krysty Wilson-Cairns partly inspired by the stories of his grandfather Alfred Mendes, a World War I veteran. The film follows two young British soldiers, Schofield and Blake, played by George MacKay and Dean-Charles Chapman, who are tasked with delivering a critical message across enemy territory on the Western Front. If they fail, 1,600 men will walk into a German trap. What makes the mission feel both intimate and urgent is that the men have only hours to succeed.

The film was designed and shot to appear as a single unbroken take, a technical achievement executed by cinematographer Roger Deakins. This approach places the viewer directly behind the soldiers throughout their harrowing journey, creating a relentless sense of forward momentum and dread unlike any war film before it. The single-shot illusion required painstaking choreography, location scouting in Wiltshire and Hankley Common, and precisely coordinated lighting changes for day-to-night transitions. Every hiding cut had to be invisible to the eye.

1917 received extraordinary critical acclaim and became a major commercial success, grossing over $385 million worldwide. It won three Academy Awards including Best Cinematography for Roger Deakins, Best Sound Mixing, and Best Visual Effects. The film also won the Golden Globe for Best Picture Drama and Best Director, cementing Sam Mendes's reputation as one of the most technically ambitious filmmakers working in Hollywood today.
