Spies discover that the Red Chinese have built a "doomsday machine" capable of destroying the surface of the Earth, and that they plan to use it within a matter of days. Meanwhile, Project Astra, a manned U.S. space mission to Venus, is in its final hours before launch when it is taken over by the military and nearly half of its all-male crew is replaced by women. The reason for this becomes apparent when, shortly after Astra leaves orbit, the Earth is completely destroyed in a global cataclysm! Is the human race doomed? What dangers and wonders await the crew of the Astra on their journey to Venus? Written by yortsnave

SO bad, it's really funny!
17 August 2000 | by yortsnaveSee all my reviews

I bought the video because the plot sounded like an adaptation of a great mid-1960s comic book I own, one of my prized possessions. Alas, I was wrong. This movie is SO bad, it's quite funny!

Where can I start? The movie begins with an Oriental cold-war/espionage plot, followed by a military end-of-the-world scenario (with Casey Kasem as a Mission Control Capcom!), then becomes a battle-of-the-sexes-in-outer-space flick, finally ending with a bizarre philosophical encounter with a superior alien intelligence.

The special effects are laughable--Barcaloungers or La-Z-Boys are used for crew couches in the spaceship; two entirely different craft (a V-2 -like rocket and a circular space station) are supposed to be exterior views of the SAME spaceship; and the Apollo CSM serves as a Russian interplanetary craft with a quite-spacious interior.

Character development is not much better. One of the main male leads, supposedly one of the astronaut corps' finest, becomes a sex maniac the minute he leaves Earth orbit.

Highly recommended for all who love bad movies!
