When Worlds Collide

A scientist concocts a frightening theory about two planets rotating around each other in outer space. He believes that one of the orbs is destined to crash into planet Earth, thus destroying life as we know it. But he also has a plan. The astronomer teams up with a sympathetic pilot, and the two construct a sort of modern space ark. They hope it will save a lucky group of humans by flying them all to safety on the surface of a surviving planet. (official distributor synopsis)
