King Solomon's Mines is a 1937 movie, the first film adaptation of the 1885 novel by the same name by Henry Rider Haggard. It starred Paul Robeson, Cedric Hardwicke, Anna Lee, John Loder, and Roland Young. The film was produced by Gaumont British Picture Corporation, adapted by Charles Bennett (uncredited), Michael Hogan, Roland Pertwee A.R. Rawlinson (uncredited) and Ralph Spence (uncredited). It was directed by Robert Stevenson.
The 1937 film follows the original novel faithfully, except for some musical interludes deliberately added to give Paul Robeson a chance to sing. The more famous 1950 Technicolor version severely alters the tale to make Allan Quatermain into a romantic hero who falls in love with the heroine, whereas in the original film Cedric Hardwicke played him as a professorial type completely uninterested in romance. -Wikipedia
