The film is told from three points of view: on the beach with the infantry (including Fionn Whitehead and Harry Styles), the evacuation by the navy (featuring Cillian Murphy and Mark Rylance, showing how civilians came to the rescue) and then in the air (with Tom Hardy engaging in plane combat).
Speaking about the narrative structure in Premiere magazine, Christopher Nolan stated: "For the soldiers who embarked in the conflict, the events took place on different temporalities. On land, some stayed one week stuck on the beach. On the water, the events lasted a maximum day; and if you were flying to Dunkirk, the British spitfires would carry an hour of fuel.
To mingle these different versions of history, one had to mix the temporal strata. Hence the complicated structure; even if the story is very simple. Do not repeat it to the studio: it will be my most experimental film."
