Watch Gemma Arterton in the trailer for Their Finest

Directed by Lone Scherfig and written by Gaby Chiappe, the film is based on the 2009 novel Their Finest Hour and a Half by Lissa Evans.

In 1940, a married woman (Gemma Arterton) and a screenwriter (Sam Claflin) develop a growing attraction while working together on a propaganda film about the evacuation of Allied troops from Dunkirk, France.

The film stars Gemma Arterton, Sam Claflin, Bill Nighy, Jack Huston, Jake Lacy, Richard E. Grant, Henry Goodman, Helen McCrory, and Claudia Jessie.

Hillary and Amanda both saw the film last year at the Toronto International Film Festival and London Film Festival respectively. They both loved it.

I have been sent the trailer and you can watch it below.
