This is the only Spanish-language film in the entire original Chan series and the only one that doesn't feature Warner Oland as Charlie Chan. There were no other foreign-language Charlie Chan films made by Hollywood after this one because, shortly after this movie came out, a method of putting sound on the actual film was developed, and so voice dubbing became more practical.
A copy of this film survives at the UCLA Film and Television Archive.
Some in Spanish-speaking audiences would have guessed or suspected the model for "Capitan" Roland Kin, played by José Nieto. Kin, like the good-looking Don Garcia in Juan Ruiz de Alarcón's play "La Verdad Sospechosa" ("The Truth Suspected"), (written between 1618 and 1621; published in 1634), is an incorrigible liar. Both "Capitan" Kin and Don Garcia lose the affections of a woman by their fibbing.
This film is found on the Twentieth Century Fox's Cinema Classics Collection DVD of "Charlie Chan in Shanghai" (1935).
This photograph of Chan's large family is the same one that also appears in other Charlie Chan movies.
