When it comes to war movies, there’s plenty about World War II but far, far less when it comes to chronicling its bloody predecessor. What exists is pretty rich and powerful, including classics such as “All Quiet on the Western Front” (1930), “Gallipoli” (1981, and a classic!) and “Paths of Glory” (1957), which all captured the barbaric horror of trench warfare – inhumane hellholes of mass slaughter where heroics were measured by the last man standing. A couple of years ago, Peter Jackson fittingly embraced those lost heroes with the cinematic ode “They Shall Not Grow Old,” the “Lord of the Rings” director’s first documentary; and looking to add to that list, director Sam Mendes (“American Beauty” and “Skyfall”) drops a taut, fast-paced shot of adrenaline on us in “1917,” which might not be long on plot, but pins you to the edge effectively as the clock ticks and ordinance explodes overhead.

Much will be made about the long-shot cinematography by Roger Deakins (“Fargo” and an Oscar winner for “Blade Runner 2049”). It’s absolutely brilliant, and any of those pooh-poohing it as a gimmick likely don’t understand the technical complexity involved. Deakins’ artistry gets put on display from frame one as we meet up with young lance corporals Schofield (George MacKay) and Blake (Dean-Charles Chapman) lazing wearily in a field. Brought bleary-eyed before their C.O., they’re ordered to deliver a message to another allied outpost several clicks away: The grim circumstance of the situation is that communications are down, and if they fail to make the drop before the next sunrise, some 1,600 British soldiers will march into a trap and be slaughtered. Blake’s brother, as we’re informed, is among the unaware – the sense of urgency’s not just paramount, its personal. 

From that brief, officious interlude, we’re off, following the lads down into the trenches, through the bomb burst, across the wire and into German-controlled French countryside. Along the way, mangled corpses hang from barbed wire entanglements and bob in the mud pits and streams they must cross. Then there’s the close encounters with the enemy, including the pilot of a downed biplane, when a brief moment of humanity turns deadly. The whole harrowing ordeal unfurls in real time, with the two constantly flushed, harried and under fire. In its pressure-cooked pace, “1917” invokes the same fraught “what could possibly go wrong next?” anxiousness that “Uncut Gems” rattled us with just weeks ago. 

What’s most impressive about Mendes’ salute to valor is the seamless synergy of choreography, action and sound (both ambient and Thomas Newman’s soul-shaking score). It’s an immersive effect that embeds you with the soldiers as if you were there, following as they charge through the trenches and duck enemy fire. That POV, while wholly visceral and unique, also makes “1917” feel a bit like a video game, in which depth of character becomes secondary to the next eye-popping visual. Chapman and MacKay are plenty fine, mind you; they’re just not given the theatrical real estate to expand. It’s all action, all the time. Pauses along the frenetic path do give us a chance to breathe when the pair check in with higher-ups (played by Colin Firth, Benedict Cumberbatch and Mark Strong), but then it’s onto the next bullet-blazing gauntlet.
