South African bush pilot and carefree ladies man Dave Randall finds he has been let in on the greatest and most terrible secret in the world when an eminent astronomer pays him to deliver some mysterious photos from to an equally prominent colleague in the U.S. The recipient, Dr. Hendron, confirms the awful findings of the sender: the star Bellus will collide with Earth, destroying our planet. Despite widespread disbelief, Marston and Spiro, a pair of millionaire philanthropists, give Dr. Hendron all their assets to begin construction on a huge rocket ship that will, at least theoretically, transport a nucleus of survivors to Zyra, a planet which orbiting Bellus that may or may not be habitable. The funds aren't enough to complete the spaceship, and Dr. Hendron solicits a contribution from elderly wheelchair-bound tycoon Sydney Stanton, a wheelchair-bound old man who, unlike the selfless Marston and Spiro, demands a place on the rocket, even though space and weight will be too ...

Did You Know?


George Pal wanted to film the novel's sequel, "After Worlds Collide," which depicted the struggle of human survivors on the alien planet. However, the failure of his film Conquest of Space (1955) badly damaged his career and the sequel was never made. See more »


Throughout the film, Bellus is referred to as a star; this is presumably how life is able to be sustained on Zyra. However, if this was the case, Earth would have been destroyed from the heat long before Bellus collided with it, even if it was a small brown-dwarf star. See more »

Narrator: [spoken over a shot of outer space] Needles in a heavenly haystack. There are more stars in the heavens than there are human beings on Earth. Through telescopes men of science constantly search the infinitesimal corners of our solar system seeking new discoveries, hoping to better understand the laws of the Universe. Observatories dedicated to the study of astronomy are set in high and remote places, but there is none more remote than Mt. Kenna Observatory in this part of South ...

Money to burn!!!!
1 March 2002 | by (USA) – See all my reviews

This movie rocks!

Okay, I know it's dated. know what?? I Don't care! This kind of movie making would put half the people in Hollywood out of work today. Maybe that's not such a bad thing. They did it right in the early days. They had their priorities right:

Story first

Then characters

Then Special effects

Seems simple, doesn't it? How come they can't get it right today? (with few exceptions, of course). Nope, today it's Special effects, stars, then story.... in fact, even the stories aren't original!!!

This sums up why I like this movie so much and many like it from the same era. They're exciting, fun, and captivating. The kind of movie that leaves you thinking, dreaming, having nightmares, all in the name of fun. You're left dreaming of what it would be like, how you'd react, what you'd do. You'd sit and ponder about a new life on a new planet. And not once would the level of special effects tarnish your view of this gem.

When was the last time you felt that way coming out of a modern movie? My guess is a lonnnnnng time. There are very few exceptions today. The special effects in movies like "Worlds" was icing on the cake... BUT IT WAS THE CAKE THAT MATTERED! Today, it's all icing and the cake can't support it (crappy icing, in fact!!)

Eat your cake and have it too! Watch "When Worlds Collide"!
