But despite the umbilical connections to all these cinematic progenitors, Dunkirk is first and foremost very much its own thing: a unique, bold, experimental film which - while probably not quite Nolan's greatest achievement - could only have been made by someone with his clout and ambition. And given that, for me, Christopher Nolan's ambition often outstrips his storytelling abilities (unpopular opinion: Inception, The Dark Knight Rises and Interstellar are all loaded with promise but trip over their own narrative shoelaces), it's a welcome relief that this time he's crafted more of an experience than a story. Virtually ditching characterisation and traditional notions of narrative, Dunkirk is less a movie than an ordeal. And I mean that, for the most part, in a good way.
That opening scene sets the tone for the next hundred minutes: tension, disorientation, a hidden enemy and extremely loud noises are very much the order of the day. A disparate bunch of unknowns spend the next week desperately trying to get the fuck out of France and back home in one piece while Nolan amusingly forces Big Names to stay in one place and do very little: Spitfire pilot Tom Hardy barely leaves the confines of his cockpit-set close-up, Cillian Murphy shivers with PTSD, Mark Rylance is stuck at the wheel of his fishing boat and Ken Branagh stands on a pier looking stoic. Even Michael Caine is relegated to a voice cameo.
It's odd, then, that Dunkirk remains a bloodless affair. Nolan's decision to focus on suspense rather than the flying limbs and guts of, say, Saving Private Ryan's visceral opening and closing scenes lend it an incongruous air of false safety at odds with the thick seam of authenticity running through the rest of the film. It's a minor quibble, but the odd splash of claret could have upped the stakes even further. Instead, in an effort to heighten the tension, Nolan allows Hans Zimmer the freedom to carpet bomb the film with his most ludicrous, histrionic and distracting score yet. Barely a scene goes by without screaming strings or electronically enhanced horns blasting out at comically overblown volume, wilfully overlooking the dramatic effect that a well-placed moment of silence or two can bring.
Fortunately, Nolan's eye for a shot more or less makes up for his cloth ears. There are images in Dunkirk of such aching wonder - especially if witnessed on the appropriately majestic scale of an IMAX screen - that blow the mind. Dogfights between the RAF and the Luftwaffe are reminiscent of George Lucas' best X-wing moments (ironically, since Lucas shoved footage of WWII films into Star Wars before aerial sequences were finished), the beaches of Dunkirk stretch off into infinite bleakness and the scale of everything is brain-boggling. Tiny figures of men dot the vast expanses of sand, ridiculously tiddly fishing boats pootle across miles of unforgiving English Channel to aid the rescue, and even those Spitfires and Messerschmitts find themselves almost lost against the beauty of a clear, bright sky. The idea that all this is somehow cosmically futile is expressed with elegant awe.
Nevertheless, Dunkirk is quite an achievement even by Christopher Nolan's standards. It's a commendably original, ruthlessly effective sensory assault that pushes mainstream cinema further than anything else has for a long time, and that's not to be underestimated. It's also subtly patriotic without being jingoistic, especially in its treatment of the ordinary folks back home who risked their lives sailing their rickety tugboats across the Channel to pick up complete strangers in dire need. The Dunkirk spirit soaks through every frame, and it's a timely reminder that if we're so desperate to get away from Europe then we're going to need every drop of it.
