World on Fire (2019)
1 visible crew/equipment mistake in season 1
Starring: Sean Bean, Helen Hunt, Jonah Hauer-King, Julia Brown
Factual error: After escaping from Danzig, Grzegorz and Konrad flee to Warsaw, then to the eastern, Soviet-occupied part of Poland. They then make their way on foot right across occupied Poland and Germany to join British forces at Dunkirk, a distance of over 1,000 miles. Not a likely journey on foot at any time, let alone across hostile territory in the middle of a war.
