Written as a bet that he couldn't come up with a better adventure story than Treasure Island, H. Rider Haggard's King Solomon's Mines has proved itself a hardy perennial over the years without ever getting a particularly faithful screen adaptation. MGM's 1950 version more or less keeps to the bare bones of the story, but changes the reason for the quest and those on it - not a pure treasure hunt but a search for Deborah Kerr's missing husband who may or may not have met his end searching for the fabled mines. Stewart Granger's fine as her reluctant guide Allan Quatermain (a role originally intended for Errol Flynn, who wasn't physically up to the rigors of difficult location shooting), going purely for the money but gradually thawing enough to start hoping that Kerr really is a widow.
Most of the novel's action is missing, though the climax is still present and correct, but it's still a surprisingly entertaining star vehicle that holds up much better than its reputation might lead you to believe. The film's big selling point is that it was actually shot on remote African locations, quite an achievement with the unwieldy Technicolor cameras of the day. As a result there's a travelogue feel to much of the film as it goes out of its way to stress that they're not on the backlot even though there is a fair bit of back-projection in the big stampede sequence. (MGM had enough footage left over for another three films, with Watusi, the dire 1959 Tarzan the Apeman and the 1973 remake of Trader Horn all making much use of it to keep their costs down.) It may perhaps be a little tame for those raised on Indiana Jones, but if you're not expecting a cliffhanger every reel you'll find a lot to enjoy.
The only extra is a trailer, which boasts a score by Miklos Rozsa (the film has no score at all beyond local African chants).
