Revealing mistake: The shot in the station is somewhat revealing, not only a modern diesel train (as already reported) in 1914 but also a third electric rail. (01:05:15)
Visible crew/equipment: In the scene where Sir John is talking to Harry Smith, as the carriage drives off, you can briefly see a modern vehicle in the window. It is a white SUV. (01:08:25)
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.
