Sherlock Holmes and the Secret Weapon (1942)
1 question
Directed by: Roy William Neill
Starring: Basil Rathbone, Nigel Bruce, Lionel Atwill, Kaaren Verne
Continuity mistake: Holmes says "One last warning" and looks at the Nazi on his left. In the next shot, he's now looking at the Nazi on his right. (00:03:48)
Trivia: Lionel Atwill, who plays Professor James Moriarty, had already played Dr. James Mortimer in the 1939 movie "The Hound of the Baskervilles," with Basil Rathbone and Nigel Bruce.





Chosen answer: It's possible. Even during WWII, people were less savvy about protecting personal information, particularly as asking for a home address seems innocuous enough as opposed to giving out government or military info. Of course, this is a movie, so some liberties are taken to serve the plot.
