Why do you think that people like films? It’s because stories are structured; have a shape, a purpose, a meaning; and when things gone bad they’re still a part of a plan; there’s a point to them. Unlike life. In 1940 London former secretary and comic strip writer Catrin Cole (Gemma Arterton) is hired by the Ministry of Information to insert more realistic female banter in propaganda films. She’s shacked up with failing war artist Ellis Cole (Jack Huston) who becomes jealous of her job while he can’t get an exhibition of his work. She starts working on a story from the newspapers about identical twin sisters who supposedly rescued soldiers at Dunkirk but discovers it was exaggerated. While she is struggling with the screenplay she falls for screenwriter Tom Buckley (Sam Claflin) and rows with self-centred actor Ambrose Hilliard (Bill Nighy) whose career is basically at an end. All the while the German bombs rain down on London and they’ve got to use an American war hero (Jake Lacy) who’s never acted before , turning journalistic fiction into a movie to entertain the masses and get America into the war … There’s a great idea buried here under a mound of rubble caused by the German bombs. Gaby Chiappe’s adaptation of Lissa Evans’ novel Their Finest Hour and a Half can’t decide whether it’s a comedy or a drama and at its heart is an issue of research – and the lack of it. There are some good insights into the kind of wartime propaganda inserted into films of the era and nice pastiches but they’re overly obvious. The second (major) death is quite laughable which is presumably not what was intended. Rachael Stirling offers some terrific oppositional feminism as Phyl from the Minstry and Nighy steals every scene as the actor who turns out to be human after all. Jeremy Irons enjoys himself as the Secretary of War. Another somewhat tentative tragicomic British film from Danish director Lone Scherfig (after An Education and One Day) with Arterton more or less delightful in a performance which attempts depth but drops the Welsh accent PDQ and Nighy gives his best Leslie Howard, sort of. Harmless and inoffensive irony which I suppose is a kind of propaganda in itself.
