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 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.
