'Dunkirk' movie trailer shows desperate World War Two rescue

Warner Bros. has released the first full trailer for Christopher Nolan's upcoming movie 'Dunkirk', where former 'One Direction' member Harry Styles makes his feature film debut as a young soldier. The much-awaited drama follows young soldiers during the evacuation of Dunkirk in France during the Second World War.
The two minutes and 18 seconds long trailer gives us a look at the horrifying situation the British, French and Belgian soldiers were put in when they found themselves trapped on the French coast by German forces.
Christopher Nolan directs the movie, which recreates Operation Dynamo, in which some 338,000 soldiers were rescued between May 27 and June 3, 1940, by warships and a flotilla of pleasure boats and other small craft.
Described as a "miracle of deliverance" at the time by British Prime Minister Winston Churchill, the 1940 evacuation was considered as one of the several key events that determined the outcome of World War Two.
Also starring Tom Hardy, Mark Rylance, Kenneth Branagh, 'Dunkirk' is due to open in movie theatres on July 21, 2017
