Did You Know?


There was a sequel to this film in the works in 1956. Screenwriter Franklin Coen and producer William Alland submitted a script titled "Aliens In The Skies" to Universal Pictures, and for a short time it was announced as in "pre-production development" at the studio. However, the studio boss, Edward Muhl, shot down their proposal when he looked over the proposed budget for the film, to be shot in Technicolor and CinemaScope, and to co-star Rex Reason and Faith Domergue reprising their roles, to be released in 1957. It was too expensive, he said. Muhl's idea of a science-fiction movie in the 1950s was a cheaply-made B-movie with a monster in it for the kids. See more »


The sequence described starts at ~1:23:40 into the film. When the aircraft in which Drs. Meacham and Adams make their escape from the saucer is viewed in the bay, the number shown (N97422) is on the right upper wing. When the aircraft is released, and banks away, the number is on the left wing and is mirrored. The film was apparently inadvertently reversed. See more »

not as bad as reputed to be
14 February 2004 | by (Mississippi, United States) – See all my reviews

Boy I never imagined I would be in the minority of those who thoroughly enjoyed this sci-fi effort. Sure,it doesn't have the greatest visual effects,but I always thought it was creative with what it had. The film was made quite a long time ago and I respect the makers for trying to create an imaginative little exercise in the vast genre of science fiction. It does have pretty good acting though the aliens are stiff,but were they meant to be lively? The film isn't poetry,but I love these type of cheesy sci-fi films and think this one is an A-class B-picture. ****/*****
