Christopher Nolan has called upon frequent collaborator Cillian Murphy to star in his WWII action thriller Dunkirk, according to The Wrap.
Murphy – who has already worked with Nolan on The Dark Knight trilogy and Inception – will play a supporting role in a star-studded British cast that includes Tom Hardy, Mark Rylance and Kenneth Branagh.
The trio will lead a selection of younger stars, with Aneurin Barnard and Jack Lowden already signed up alongside newcomer Fionn Whitehead and One Direction singer Harry Styles, making his acting debut.
As the name suggests, Dunkirk will chart the mass evacuation from northern France during the Second World War, a military action known as Operation Dynamo which saved the lives of 330,000 Allied soldiers surrounded by German troops.
Nolan wrote the film which is set for worldwide release on 21st July 2017.
