When a film credits the novel and its writer but then gives a totally different writer a "Story by" credit (in this case co-scripter Edward Harper) you know the original source has been junked. Indeed, there is almost no correlation between this film and the 1931 original or the novel. In fact, the filmmakers have simply taken the title and its main character and grafted him onto the H. Rider Haggard story of 'King Solomon's Mines.' As for the film itself, it boasts in its end credits that plenty of African locations were used... but that's mostly, if not all, Second Unit material. The actors seem to have been filmed on stage sets or at Southern California locations (wild animal park/nearby desert dunes). Lots of process screen work and indoor settings, although the African footage is good. And Rod Taylor is perfect casting as Trader Horn. You can believe him as a rough-hewn, know-it-all, wheeler-dealer and reluctant guide. Less believable is his romance with Heywood. And Don Knight, as the British commander ceaselessly hunting for Horn, whom he's branded a "traitor to England in a time of war" (it's 1916), is almost buffoonish, as if channeling Malcolm McDowell through a 'Carry On' film. The African natives are a mix of obvious Hollywood actor types and real natives (many just stock footage or Second Unit). Much of the scenic stuff doesn't match up with the actors, and the plodding story never catches fire. Why MGM felt this would be a success at the box office is hard to fathom.
