World War I, The Seminal Catastrophe of the 20th Century, hasn't spawned nearly as many films as did the Second World War that was to follow only 20 years later. For every Warhorse, Lawrence of Arabia, and All Quiet on the Western Front, there are troves of iconic films like Schindler's List, Dunkirk, Thin Red Line, Saving Private Ryan, Sands of Iwo Jima, The Longest Day, etc...
Perhaps this is related to the good versus evil rationale on which WWII was fought, whereas WWI had a much more nuanced and convoluted reason for its existence, i.e. a series of binding treaties that exploded into a global war.
In the newest WWI film, 1917, the overarching causes behind why the soldiers are in trenches become irrelevant thanks to an expertly-crafted, human story that envelops the viewer with a common principle found in all wars and in the films that depict it; you fight for the soldiers next to you. Along with sharp performances and thoughtful writing, the filmmakers enlist a technique as difficult to achieve as it is powerful in its reception; a simulated single camera shot following the action from mission-start to mission-finish.
The film's use of one continuous shot (or perhaps a few hundred stitched-together shots) is designed for one specific reason; to put the audience in the shoes of two young British soldiers, tasked with carrying an urgent message of life or death to the frontlines. Effectively nullifying the safety blanket of the traditional editor where multiple shots can be combined into a film, 1917's continuous shot leaves very little room for error with the director, cinematographer, and other crew on set. In military terms, to make this film a blockbuster, Director Sam Mendez took a chance with a 0 million sniper shot, and he nailed it.
When Mendez and cinematographer Roger Deakins (both Oscar winners) decided to craft 1917 using only one shot and rely on the edit only to mask or stitch the various sequences together, they set out to bring the audience into the world of frontline war-fighting. There are no breaks. There are no pauses between frames or shots or scenes to give your brain time to catch up. The viewer is embedded with these men from mission-start to mission-finish and thus given a proximity not often afforded to audiences. The result is a visceral and captivating glimpse into the heartbreakingly painful agonies of war; especially a war as devastating as WWI. Yet, in doing so, it also provides the audience with a heightened sense of triumph as the young soldiers conquer insurmountable odds.
Whereas the creative choice of using one shot adds elemental gravitas and depth to 1917, it's execution also proves the filmmakers' dedication to this story. Due to the complexity and continuous nature of the one-shot format, the planning of every shot, performance, movement, light, wardrobe detail, effect, etc. called for the utmost military precision.
Employing the preparation, foresight, ingenuity, and assiduousness needed to lead an army into battle, Mendez and his lieutenants triumphed.
