Continuity mistake: When Churchill is delivering his first speech on May 13th, Neville Chamberlain places a handkerchief on his leg to use as a signal to his fellow MPs. During the speech you can see Chamberlain sitting a few places away from Churchill but the handkerchief is missing. Then, a short while later in the same scene, the handkerchief is back with Chamberlain's hand over it.

Directed by: Joe Wright
Starring: Gary Oldman, Kristin Scott Thomas, Lily James, Ben Mendelsohn
Factual error: Neville Chamberlain is described as chairman of the Conservative Party. He was actually party leader. Party chairman is a separate post, which was held at that time by Sir Douglas Hacking.
Winston Churchill: Those who never change their mind never change anything.
Question: In the 'War Room' scene, there appeared to be a sheet of plastic or acetate covering the wall with the map of the enemy's movements. Was that premature for plastic to be available in that size for that time frame?
Answer: It was probably Perspex, an acrylic plastic commonly available at the time, used for, amongst other things, fighter plane cockpit canopies and windscreens.
