Crack in the World
Crack in the World is a 1965 American sciencefiction doomsday disaster movie filmed in Spain. It is about scientists who launch a rocket in the Earths core to research its geothermal energy but accidentally unleash a cataclysmic destruction that threatens to sever the earth in two. It was released by Paramount Pictures on February 24, 1965.
The leader of the project, Dr. Stephen Sorenson Dana Andrews, who is secretly dying of cancer, believes that the atomic device will burn its way through the barrier, but the projects chief geologist, Dr. Ted Rampion Kieron Moore, is convinced that the lower layers of the crust have been weakened by decades of underground nuclear tests, and that the detonation could produce a massive crack that would threaten the very existence of Earth.The atomic device is used and Rampions fears prove justified, as the crust of the Earth develops an enormous crack that progresses rapidly. Sorenson discovers that there was a huge reservoir of hydrogen underground, which turned the small conventional atomic explosion into a huge thermonuclear one that was millions of times more powerful. Another atomic device is used in the hope of stopping the crack, but it only reverses the cracks direction. Eventually the crack returns to its starting point at the test site, and a huge chunk of the planet outlined by the crack is expected to be thrown out into space. Sorenson remains at the underground control center to record the event despite pleas by his wife Maggie to evacuate with the rest of the project staff. She and Rampion barely escape in time to observe the fiery birth of a second moon. Its release stops the crack from further splitting the Earth. ........
