Director Lone Scherfig (An Education) returns with this stirring romantic comedy set in Britain's wartime film industry. Catrin (Gemma Arterton) lives with her struggling artist husband in WWII-era London. Assuming she's applying for a secretarial post at the Ministry of Information, she is hired to write women's dialogue for wartime propaganda shorts. Jaded veteran screenwriter Tom (Sam Claflin) reluctantly acknowledges Catrin's value, and enlists her help in writing an inspirational film about the war effort. Endearing performances by the reluctant collaborators, and a hilarious comic turn by Bill Nighy as an arrogant actor forced to accept that he's past his prime, make Their Finest a total charmer. Setting the filmmaking crew's witty banter and comic foibles against a realistic depiction of wartime London imbues their efforts with urgency, as Scherfig creates a stealthily moving portrait of the power of cinema in times of crisis.
