Dunkirk: Official trailer for Christopher Nolan's WWII epic released

The war drama stars Mark Rylance, Kenneth Branagh and Tom Hardy

A brand new trailer for Christopher Nolan's WWII epic Dunkirk has been released, providing a deeper look at the world briefly presented in the teaser late last year.

Nolan's tenth feature tells the true story of Operation Dynamo, a daring plan to rescue 300,000 Allied troops who were surrounded by Nazis soldiers in Dunkirk during World War II.

It's early stages, but the trailer - featuring the music of composer Hans Zimmer - suggests that acclaimed filmmaker Nolan (Memento, the Dark Knight trilogy, Interstellar) has struck gold again - something corroborated by exhibitors who were stunned by footage presented to them at CinemaCon in March.

The trailer features several catastrophic scenes which look to be just a few of the film's many breathtaking yet devastating set-pieces.

Kenneth Branagh, Tom Hardy, Cillian Murphy and One Direction singer Harry Styles all appear in the trailer.

Last month, Nolan - who has been linked to Bond 25 - and editor Lee Smith opened up about the film, revealing it will be told through three perspectives featuring “little dialogue.”

Dunkirk, starring Tom Hardy, Cillian Murphy, Mark Rylance, Kenneth Branagh and Harry Styles, will be released in the UK on 21 July, a few days after its IMAX premiere.
