Did You Know?


A large device, shaped a bit like a desk, with a coiled neon tube in the center, is visible at the Ryberg Electronics laboratory. The prop was also used in the laboratories of Universal Pictures' Frankenstein films of the 1940s. See more »


When Cal and Ruth are on the ship, some aliens are leaving the compression tubes in preparation for Metaluna's atmosphere. Cal and Ruth go into the tubes to undergo the same process. If Cal and Ruth were not yet compressed, and the aliens were, they should not logically be able to be in the same room at the same time. The pressure would not be hospitable to one group or the other. See more »

A Great Film
24 February 2003 | by See all my reviews

I saw this film for the first time when I was about 10 years old and it has always stuck with me and when I saw it was on video I bought it immediately. I think that this is more than a B picture and what people have to remember is the fact that this film was made before all the great advances in special effects. Another thing that made it interesting was the fact that through the first half of the film you really didn't know if Exeter was human or alien. It wasn't until the second half of the film that we did see there was more to this mysterious group. This film is definitely an underrated classic of its era.
