Sky Captain and the World of Tomorrow (2004)

Continuity mistake: When Joseph and Polly enter the Ark, we see the door close behind them, the countdown coming to zero. The Mysterious Woman, at the time, is out cold, or at least a dozen meters behind them. Yet, she finds her way onboard the Ark somehow.

Trivia: After the robots first attack New York City, a series of newspapers is shown. On the Japanese one, you can see Godzilla's outline. (00:15:58)

Question: When the Hindenburg III docks with the Empire State Building, the newspaper shows early October 1939. Is there any clue as to what went differently in history concerning WWII?
