Besides Sidney Toler as Charlie Chan, this film's cast contained three other actors who also played famous crimefighters: Ricardo Cortez (Sam Spade in the 1931 "Maltese Falcon"), Morgan Conway (Dick Tracy in two RKO films in the mid-1940's) and Robert Lowery (Batman in the Columbia serial "The Adventures of Batman and Robin" in 1948).
Actor 'Hamilton McFadden', who plays the bit anonymous supporting role of a night clerk, formerly directed three earlier big budget entries in the series: "The Black Camel," (1931), Charlie Chan Carries On" 1931), and "Charlie Chan's Greatest Case" in addition to starting "Charlie Chan in Paris" (1935).
The opening lines of the song 'Someone's Ballad' by singer/songwriter Paul Murphy - "She pulled into the Hotel Sierra/White-heeled and hollow-eyed" - come from Pauline Moore's arrival at her hotel in this film.
The twenty-first of forty-seven Charlie Chan movies.
Final film of actress Louise Henry.
