Atonement (2007)

Darkest Hour (2017)

In May 1940, the fate of Western Europe hangs on British Prime Minister Winston Churchill, who must decide whether to negotiate with Adolf Hitler, or fight on knowing that it could mean a humiliating defeat for Britain and its empire.

Excellently staged with good period detail and a great cast (and Gary Oldman giving a stellar performance),  the movie isn't so exacting concerning historical accuracy - and Winston Churchill remains an enigmatic figure.
