Charlie Chan: The Scarlet Clue (1:04) 1945

Charlie Chan is back with his number three son, Tommy and his assistant, Birmingham. Charlie, working for the federal government, is investigating the possible theft of radar secrets. The war is still going on and radar is helping the aircraft bombers to drop their load on targets without the crew actually seeing the target. The radar lab is in the same building as a radio and television station. This came as a surprise to me because I didn't realize that television was broadcasting in 1945. Chan investigates the actors and actresses at the radio station. There are scenes of the cast rehearsing around the microphone. Chan finally gets the murderer and the secrets of radar are again safe. This was a pretty good movie for a B movie. For those unfamiliar with the term B movie, it originated quite awhile ago. B movie is a term for a low-budget movie, they were made to be part of a double feature and are always shorter in time than the feature. The Charlie Chan movies are a perfect example of  B movies.
