Watch: Harry Styles struggles for life in first trailer of Christopher Nolan's 'Dunkirk'

Warner Bros. recently released the first full trailer of Christopher Nolan's upcoming movie Dunkirk where former 'One Direction' member Harry Styles stars as a young soldier during WWII.

Styles' character does not speak any dialogue in the two minutes and 18 seconds long trailer but one scene shows him gasping for breath underwater.

The much-awaited drama follows young soldiers during the evacuation of Dunkirk in France during the Second World War. As German soldiers advanced across Europe in 1940, the Allies were pushed to the French coast. Thanks to the collective effort of the British, Belgian, and French forces, more than 330,000 soldiers got away.

According to The Guardian, Nolan's film is the first since 1958 to focus on the "miracle of the little ships", the evacuation whereby over 300,000 Allied soldiers were rescued from Dunkirk's harbour and beaches in 1940, after they had been cut off by the rapid German invasion of northern France.

Also starring Tom Hardy, Mark Rylance, Kenneth Branagh, Dunkirk will be initially released in UK and US cinemas on July 21, 2017.
