An astronaut comes back to Earth and crashes in a field, incredibly irradiated and wreaking havoc. Just as they have him cornered, he disappears, and the "real" astronaut is found 7,500 miles away in the Pacific Ocean, "alive, well, and of normal size." Written by Jonah Falcon <>

Henry Hite was 7 foot 6, but the director wanted the monster to be 10 feet tall, so Hite was filmed at an upward angle in every shot. See more »

The 2nd Worst Movie Ever.
16 November 2002 | by (PA) – See all my reviews

I saw this one on MST3K years ago, and I can still remember how bad it was. This movie has to be the 2nd worst movie of all time (trailing "Manos: The Hands Of Fate" for that title), and there's a great reason for that...

First off, the plot. It's atrocious. There isn't REMOTELY a monster whatsoever in this film. The acting, like other bad movies is also bad as well. This movie overall was bad, so bad that it should've been destroyed after it was done. Overall, a extremely, awful, botched waste of film, and precious time...

Only watch this on MST3K. They bashed it good on that show.
