In the early part of World War II, Catrin Cole (Gemma Arterton) is hired as a scriptwriter to accurately portray women’s dialogue in propaganda films. The war office wants these films to strike the right balance of realism and optimism, boosting morale throughout Britain (oh, and inspiring the United States to join the war). In Their Finest, Catrin works closely with fellow writer Tom Buckley (Sam Claflin) and aging film star Ambrose Hilliard (Bill Nighy) during the Blitz in London to contribute to the war effort. Based on the novel of the same name by Lissa Evans. Discover other movies set on the home front during WWII.
