Warner Oland returns as wily, philosophical oriental detective Charlie Chan in this expensive-looking series entry. This time, Chan follows the trail of clues when a "respectable" Honolulu businessman sidelining in blackmail and other unsavory activities is murdered. Like the earlier Black Camel, the film was made virtually in its entirety in Hawaii, save for a brief expository scene in San Francisco. Alas, this is one of four "Chan" films that apparently no longer exist, but stills and existing publicity material indicate that it was an elaborate production, faster-paced than usual, with Heather Angel attractively garbed in a swimsuit in most of her scenes. A few outtakes of Charlie Chan's Greatest Case were preserved for a Fox Studios "blooper" reel, showing Warner Oland reacting in hilarious rage as he muffs his lines.
