The language spoken by the native characters, and by Juanita (Dorothy Burgess) when she addresses them directly, is Kreyol (also spelled Creole), the African-influenced dialect of French that is the common language of Haiti.
This was one of the final horror films to be released before the Hays Code was strictly enforced. The film was released on June 15, 1934 and the strict enforcement of the Hays Code began little more than two weeks later, on July 1, 1934; the change forced films released after that date to obtain a certificate of approval. If this film had been released just a bit later, many elements would have had to have been amended.
Not counting mystery films, this marks the final horror film of Fay Wray's career. Wray has been considered one of horror's first and best "scream queens" and is undoubtedly best remembered for her contributions to the genre. Despite maintaining an active presence in film and television for more than forty-five years after making this film, this was Wray's horror swan song and capped her contributions to the genre rather early in her career.
The film was refused a UK cinema certificate in 1934.
This film left little impression on star Fay Wray. In an interview some years after making the film, Wray admitted that she had little memory, if any, of making the film at all. She had essentially forgotten that she appeared in it. Wray also claimed that she never watched the film at any point in her life.
