This movie often portrays Churchill as a doddering old fool: He was anything but that! I've read other books on Churchill, listened to his speeches and film clips; this movie misses more than it hits. There are several Darkest Hour fact checking websites dealing with the accuracy of the events, timelines, relationships, and characters' personalities; they also found the movie interesting but lacking. For instance Churchill's famous "We shall fight them on the beaches" speech was made six days after the rescue of the troops from Dunkirk, not before. His confidence came because England had received back 300,000 of her troops and not merely hopeful but empty bravado. The idea of using private vessels to help rescue soldiers was not originally Churchill's; the Admiralty had the idea and preparations in place weeks ahead of the event. Don't prep for a history test based on this movie.
