Storyline

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 ...

Goofs

While a planet making a close pass at Earth would effect the tides and cause disruption, the film presents it incorrectly. The disruption would not occur at one moment. There would be a build-up of disruption in the tides until the planet makes its closest pass, causing maximum damage. See more »

a wonderful sci-fi film because it ultimately looks at human nature
12 June 2005 | by MartinHaferSee all my reviews

This is an often overlooked sci-fi movie from the 50s--being not nearly as famous as the excellent Day the Earth Stood Still or Invasion of the Body Snatchers. Despite this, it is still one of the best ones of its era. The basic story is good, but not great. What sets it apart are the characters within it and the insight into human nature it gives you. This makes the film very allegorical and makes you think. Many of the characters, such as the leads, rise to the occasion and only think of saving others when it appears most life on Earth will be destroyed. Then, there are the jerks who also show their true colors--such as the crowd who try to storm the space ship bound for a safe new world, and especially the evil old financier who who wants to save his own skin and could care less about others. John Hoyt plays this role beautifully and it is very, very much like the character C. Montgomery Burns from the Simpsons!

Oh, and lest I forget, for 1951, the special effects are absolutely amazing. Aside from a pretty flat-looking matte painting used at the end, the space ship effects and flood effects were just terrific and earned this movie a well-deserved Oscar.

This is a great sci-fi film that all fans of the genre need to see.
