Factual error: At the end of the 'Goodbye' the men all board a train which leaves along a track on a seaside pier. The shot changes from this stylised vision to a shot of an Edwardian Lady alone on a railway platform. In the background is a 1970s, ie. modern, diesel train.
Factual error: The sign very blatantly says 'World War One'. They didn't call it World War One at the time - they didn't know there was going to be another one. Similar to the old thing about coins having BC on them when they had no idea Christ was coming.
