Production slated for July.

Director Tom Harper and his ‘The Scouting Book for Boys’ scribe Jack Thorne are said to be reuniting for the London-set thriller ‘War Book.’

Per Screen Daily, the story deals with “the aftermath of an international nuclear attack, played out in the political backrooms of London.”

Lauren Dark of Sixteen Films is on board to produce alongside Mike Brett and Steve Jamison of London-based Archer’s Mark.

Principal photography is scheduled for July, ahead of Harper’s ‘Woman in Black’ sequel ‘The Woman in Black: Angel of Death.’
