Following its world premiere in front of British Royalty last night, the first reactions to Christopher Nolan’s Dunkirk have started to come it – and it’s largely good news. The film, which tells the true story of the evacuation of Dunkirk during World War II, is getting praise across the board, particularly for its cast.

Here are some of the initial reactions via Twitter.

Dunkirk opens as hundreds of thousands of British and Allied troops are surrounded by enemy forces. Trapped on the beach with their backs to the sea they face an impossible situation as the enemy closes in.

The film’s ensemble cast includes Fionn Whitehead, Tom Glynn-Carney, Jack Lowden, Harry Styles, Aneurin Barnard, James D’Arcy and Barry Keoghan, with Kenneth Branagh, Cillian Murphy, Mark Rylance and Tom Hardy.

The film opens in cinemas on July 21st, 2017. Check back for our full review of the film next week.
