Gemma Arterton, Sam Claflin and Bill Nighy to embark on 'Their Finest Hour And A Half'

Gemma Arterton, Sam Claflin and Bill Nighy are coming together for 'Their Finest Hour And A Half.'

The project, which will be helmed by Lone Scherfig, is being developed and co-financed by BBC Films, as Oscar-nominated producers Number 9 Films and Wildgaze Films produce, Deadline.com reported.

Based on Lissa Evans's 2009 novel, which is set in early 1940s World War II London, the romantic comedy was adapted by Gaby Chiappe, and will be executive produced by BBC Films' Christine Langan and Ed Wethered.

Hanway managing director Thorsten Schumacher, who'll be handing the worldwide sales rights, said that the film was a funny and touching romance with a great female lead role that is entertaining and emotional in equal measure.

The movie will begin shooting in late summer 2015.
