Dunkirk opens as hundreds of thousands of British and Allied troops are surrounded by enemy forces.Trapped on the beach with their backs to the sea they face an impossible situation as the enemy closes in. Dunkirk features a prestigious cast, including Tom Hardy, Mark Rylance, Kenneth Branagh and Cillian Murphy, as well as newcomer Fionn Whitehead.The film was written and directed by Christopher Nolan, best known for his work on Inception, Interstellar, and the Batman trilogy. In May 1940, Germany advanced into France, trapping Allied troops on the beaches of Dunkirk. Under air and ground cover from British and French forces, troops were slowly and methodically evacuated from the beaches as part of Operation Dynamo. They used every serviceable naval and civilian vessel that could be found and, at the end of this heroic mission, 330,000 French, British, Belgian and Dutch soldiers were safely evacuated.
