Christopher Nolan’s cinematic wartime drama Dunkirk has soared to the top of the UK box office on its opening weekend debut.

The film, which follows the evacuation of British forces from the beaches of 1940 France, earned an estimated £9.5m across 637 UK cinemas.

That figure includes £1.3m taken at IMAX venues after Nolan suggested the format would offer fans the best possible viewing experience.

“Critics and audiences alike agree that Dunkirk must be seen on the biggest possible screen, and we anticipate that the incredible response among audiences across the UK will drive continued success well into the summer.”
