Watch Harry Styles drowning in dramatic ‘Dunkirk’ film trailer

See a glimpse of Christopher Nolan's war epic

Watch the first full trailer for Christopher Nolan’s upcoming Dunkirk film.

Dunkirk, Nolan’s follow-up to 2014’s sci-fi drama Interstellar, is due to open in cinemas on July 21, 2017. The film’s story is set in World War II during the Dunkirk evacuation.

The movie has an ensemble cast that includes Cillian Murphy and the acting debut from One Direction’s Harry Styles.

Watch the trailer in full below. It sees Styles’ character appearing to drown at the 1.53 mark.

As well as Murphy and Styles, the film also stars Tom Hardy, Mark Rylance, Kenneth Branagh, Fionn Whitehead, Jack Lowden, Aneurin Barnard and James D’Arcy.

Nolan – director of The Dark Knight and Inception – is directing from a script he wrote himself, and his regular collaborator Hans Zimmer is writing the film’s score.

The film was shot in France, Urk in the Netherlands, Swanage and Weymouth in the UK and Los Angeles in the US.

It was reported by IGN that Nolan spent $5 million (£3.8 million) of the film’s budget on a vintage World War II aircraft which he plans to crash by the end of filming. The director is also understood to have had actual World War II battleships refurbished for the film to maximise its authenticity.
