The Scarlet Clue

One of the six Charlie Chan pictures Sidney Toler made for Monogram after the series left Fox. When murders pile up around a radio station that is secretly tied to a wartime espionage ring, Chan works the case while his son Tommy and chauffeur Birmingham Brown stumble through the clues beside him. The film is best remembered for the extended comedy routine between Mantan Moreland and Ben Carter, whose rhyming, never-finished conversations became a signature of the Monogram Chans. Directed by series veteran Phil Rosen, it is a brisk poverty-row mystery that keeps the plot moving and the banter constant. The film entered the public domain after its copyright was never renewed.
