Fandango sat down with director Christopher Nolan:

I think people who know the story of Dunkirk, in particular, may be surprised by the intensity of the experience. It’s a very suspenseful story and we really try to do justice to that. The pacing is relentless, and the story and action scenes are extraordinarily intense. I think the lean, stripped-down nature of that, and how fast it moves, and what it puts you through in this short space of time… I think it has a different rhythm that I’ve worked in before.
