From beginning to end, Christopher Nolan ratchets up the tension to the point of nervous exhaustion and just when you think he can't possibly raise it any higher, he finds another gear. Whether it's the Spitfires trying to shoot down the German twin-engine bomber (a Heinkel 111), before it drops its payload on the British minesweeper, or the British soldiers huddle on the mole as the Germans rain down artillery fire, or Stukas strafe them, Nolan never lets up. He never gives us a moment's respite, just as the Germans never relent. The result is a small slice of mid 20th century warfare, as well as a scaled-up panorama of one of the most pivotal moments in the history of Western Civilization. In this, he is aided enormously by the Hans Zimmer soundtrack, which sounds like a huge ticking watch. It serves to remind us of the centrality of time in this film. One of the director's motifs is to play with time and this movie is no exception. He shows us one hour of the aerial combat, one day of the small boat with its crew of the middle-aged skipper and two young men and one week of the evacuation of the troops waiting on shore. Some of my friends found the film too impersonal, but I think that was the point. These events took place on a titanic scale and Nolan found a way to render them understandable and relatable to all of us.
