Space Mutiny (also known as Mutiny in Space) is a 1988 South African space opera action film about a mutiny aboard the generation ship known as the Southern Sun. The film has since developed a cult following after being featured in a popular episode of the television show Mystery Science Theater 3000.

Plot

The Southern Sun is a generation ship, or a spacefaring vessel that contains a large number of people, whose mission is to colonize a new world. Its voyage from its original homeworld (implied to be Earth) has lasted thirteen generations, so many of its inhabitants have been born and will die without ever setting foot on solid ground. This does not please the antagonist, Elijah Kalgan (John Phillip Law), who conspires with the pirates infesting the nearby Corona Borealis system and the ship's Chief Engineer MacPhearson (James Ryan). Kalgan hatches a plot to disrupt the Southern Sun's navigation systems and use the Enforcers, the ship's police force, to hijack the ship and direct it towards this system. At this point, the inhabitants of the Southern Sun will have no choice but to accept his "generosity".
