The story takes place in 1898, but Barbara Stanwyck's hairstyle, make-up, false eyelashes, and riding pants are strictly in the 1936 mode, and, in true Hollywood tradition, remain relatively unsullied despite the many perils of the swamp and and backlot jungle through which she doggedly perseveres.
Barbara Stanwyck, though supposedly Cuban, speaks Spanish with an American accent, and English with no accent whatsoever.
