The recent Mau Mau uprising in Kenya served as story material for the 1955 British film Simba. White farmer Dirk Bogarde and his neighbors are targeted for extermination by the zealously nationalistic Mau Maus. Native doctor Joseph Tomelty, whose brother had earlier been killed under questionable circumstances, endeavors to help the whites escape the hordes, only to discover that his own father is the local leader of the insurrectionists. Given the cruelties of colonial rule in Africa, it is hard for any film to make the Mau Mau total villains, despite their own well-documented brutal treatment of their enemies. Simba downplays side-taking and ideology, choosing instead to concentrate on the adventure and suspense elements.
