The movie follows the evacuation of British, Belgian, French, and Canadian soldiers from Dunkirk during WWII, when an army of regular sea trawlers and fishing boats sailed across the French channel in order to save hundreds of troops from the advancing German troops.
Kenneth Branagh revealed that there was no sitting idle on the set of Dunkirk, and shockingly, no cups of tea, either.
The movie is told from three perspectives; soldiers on land, sailors at sea, and pilots in the air.
Branagh plays the role of Commander Bolton, the man tasked with organizing the safe evacuation of hundreds of young soldiers by sea.
