The novel has been adapted to film at least six times. The first version premiered in 1937, King Solomon's Mines, and was directed by Robert Stevenson. The best known version premiered in 1950, King Solomon's Mines, directed by Compton Bennett and Andrew Marton, which was followed by a sequel, Watusi (1959). In 1979 a low-budget version was directed by Alvin Rakoff, King Solomon's Treasure, combining both King Solomon's Mines as well as Allan Quatermain in one story. The 1985 film, King Solomon's Mines, was a more tongue-in-cheek parody of the story, followed by a sequel in the same vein: Allan Quatermain and the Lost City of Gold (1987). Around the same period an Australian animated TV film came out, King Solomon's Mines. In December 2006, the movie, “The Librarian: Return to King Solomon’s Mines” was released as the second in a trilogy that follows one man’s fantastical adventures. In 2008 a direct-to-video adaptation, Allan Quatermain and the Temple of Skulls was released by Mark Atkins, which bore more resemblance to Indiana Jones than the novel.
British comics artist Dudley D. Watkins adapted the story into a text comics series.
In 2002 a documentary was made by National Geographic Television in collaboration with Channel 4 in the UK: The Search for King Solomon's Mines.
In 2004 a TV mini-series was created: King Solomon's Mines.
