Starring Harry Carey[?] in the title role, Edwina Booth[?], Duncan Renaldo[?] (later the Cisco Kid[?]), Mutia Omoolu[?] and Olive Carey[?], the movie tells of the fictional adventures of real-life trader and adventurer Alfred Aloysius "Trader" Horn, on safari in Africa.
The fictional part includes the discovery of a lightly clad white blonde jungle queen, the lost daughter of a missionary, played by Miss Booth. The realistic part includes a scene in which Carey as Horn swings on a vine across a river filled with genuine crocodiles, one of which comes very close to taking his leg off.
The film was written by Cyril Hume[?] (dialogue), John Thomas Neville[?], Richard Schayer[?] and Dale Van Every[?], from the book by Alfred Aloysius Horn[?] and Ethelreda Lewis[?], and directed by W.S. Van Dyke[?].
It was based on a popular book of the time, Trader Horn: A Young Man's Astounding Adventures in 19th-Century Equatorial Africa by Alfred Aloysius "Trader" Horn, ISBN 1885211813.
