The film was mainly shot in the UK. Director Mendes and photographer Roger Diggins spent 9 months in preparation. Because it is mainly for location shooting, it is greatly affected by the weather, so it can only be shot with natural light. The film basically uses hand-held photography, always in motion, no scenes are repetitive, it is necessary to constantly shuttle through the field, but also to maintain the continuity of the lens, sometimes the photographer and the camera are hoisted with a steel cable to shoot a wide scene.
The whole film is a long shot and must be shot in sequential order. In order to run the show, it must be shot on a cloudy day. If it encounters a violent sun, the crew will stop work and change to a rehearsal. During the rehearsal, the crew will look up at the sky to see when the clouds can cover the sun. When the cloud came, the crew raced against time to shoot for about 5 minutes. In order to challenge the "one shot to the end" the longest shooting time is 8 and a half minutes. Then use technical means to connect multiple longer lens groups to make the whole film look like one lens.
Strictly speaking, the film can only be regarded as a "false mirror to the end"-according to statistics, the film has 22 editing points, but they are all "covered" by means of occlusion and shady, but the final effect on the screen is long. 119 minutes, very smooth long shot.
There is a scene in the film where Soldier Blake (Dean Charles Chapman) was stabbed in the abdomen by a German pilot in the farm. The director revealed that this 8-minute scene was taken more than 50 times.
