Trader Horn was the first film shot on location in Africa. It featured many authentic shots of African wildlife and a great deal of inauthentic plot. It was nominated for the Academy Award for Best Picture in 1930.

Starring Harry Carey in the title role, Edwina Booth , Duncan Renaldo, 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.
