The Day the Earth Caught Fire (1961)

Geophysicist Dr. Josh Keyes discovers that an unknown force has caused the earth's inner core to stop rotating. With the planet's magnetic field rapidly deteriorating, our atmosphere literally starts to come apart at the seams with catastrophic consequences. To resolve the crisis, Keyes, along with a team of the world's most gifted scientists, travel into the earth's core. Their mission: detonate a device that will reactivate the core.

After paleoclimatologist Jack Hall is largely ignored by UN officials when presenting his environmental concerns about the beginning of a new Ice Age, his research proves true when a superstorm develops, setting off catastrophic natural disasters throughout the world. Trying to get to his son, Sam, who is trapped in New York City with his friend Laura and others, Jack and his crew must travel to get to Sam before it's too late.

When a group of astronomers calculate a star is on a course to slam into Earth, a few days before, it's accompanying planet will first pass close enough to the Earth to cause havoc on land and sea. They set about building a rocket so a few selected individuals can escape to the planet.

A helicopter pilot and an environmental scientist lead a exodus of survivors in a search for a safe haven after a catastrophic tectonic event causes the crust of the earth to break apart.

It is just another day in the small town of Hamlin until something disastrous happens. Suddenly, news breaks that a series of nuclear warheads has been dropped along the Eastern Seaboard and, more locally, in California. As people begin coping with the devastating aftermath of the attacks — many suffer radiation poisoning — the Wetherly family tries to survive.

The world has finally managed to blow itself up and only Australia has been spared from nuclear destruction and a gigantic wave of radiation is floating in on the breezes. One American sub located in the Pacific has survived and is met with disdain by the Australians. The calculations of Australia's most renowned scientist says the country is doomed. However, one of his rivals says that he is wrong. He believes that a 1000 people can be relocated to the northern hemisphere, where his assumptions indicate the radiation levels may be lower. The American Captain is asked to take a mission to the north to determine which scientist is right.

Doctor Who and his companions are hurled into the future and make a horrifying discovery: the Daleks have conquered Earth! The metal fiends have devastated entire continents and turned the survivors into Robomen.

In the year 2022, overcrowding, pollution, and resource depletion have reduced society’s leaders to finding food for the teeming masses. The answer is Soylent Green.

Strange phenomena surface around the globe. The skies ignite. Terror races through the world's major cities. As these extraordinary events unfold, it becomes increasingly clear that a force of incredible magnitude has arrived. Its mission: total annihilation over the Fourth of July weekend. The last hope to stop the destruction is an unlikely group of people united by fate and unimaginable circumstances.

A parasitic alien soul is injected into the body of Melanie Stryder. Instead of carrying out her race's mission of taking over the Earth, "Wanda" (as she comes to be called) forms a bond with her host and sets out to aid other free humans.
