I also had remembered something about 1917 being filmed in one shot so per the wiki:
Roger Deakins was the cinematographer for the film, reuniting with Mendes for their fourth collaboration, having first worked together on
Jarhead in 2005.
[17] Filming was accomplished with
long takes and elaborately choreographed moving camera shots to give the effect of two
continuous takes.
[7][8] Although media accounts often refer to the story as being told in only one shot,
[19][20] the story cuts to black one hour and six minutes into the film, when Schofield is knocked unconscious, and fades in upon his regaining consciousness after night has fallen.
[9] Mendes explained, "it was to do with the fact that I wanted the movie to go from afternoon to dusk, and then from night into dawn. I wanted it to be in two movements...I wanted to take it somewhere more like a hallucination. Somewhere more surreal, almost dream-like. And horrifying too".
