Factual error: The underground station shown is not St. James Park, which would be 1 stop east on the District line. St. James Park has green and yellow tiles on the wall indicating District and Circle lines. The platform in the film has black and brown tiles, indicating Northern and Bakerloo lines, neither of which serve St. James Park.Crusoe

Factual error: When George VI and Churchill are having lunch at Buckingham Palace there are servants in the room.

Factual error: As they are leaving the war rooms a car can be seen parking in the background. This car is an Austin A30 and these were not introduced until the mid 50's.
