“As has been pointed out by most reviewers on IMDb, this film has all the perceived elements of cold war-period American cinema. However, what also should be considered is the influence it has had on contemporary SF movies and TV.

Hugh Marlowe, Joan Taylor and, especially, Morris Ankrum are well-known B-movie actors: they appeared in everything from Westerns to SF, with lots of stops in between. Thus, this film (complete with all the other stalwarts of ’50s and ’60s “Bs” who appear therein) can be seen as a progenitor of later low-budget productions which rely on a cheap yet capable cast.

At the time it was released (1956), Ray Harryhausen was proving his expertise with stop-motion special effects, later to be given much larger budgets in ’60s colour productions. “Gumby” and similar TV items owe much to this man, as does Aardman Productions and, possibly, Dreamworks.

It has already been indicated (by others) that “Mars Attacks” owes its saucers to this film. So, too, “ID4” has a debt, as does “Dr Who”! (Specifically the outfits worn by the aliens – that leaden ‘dome’ on top of their environment suits belongs to a famous adversary of the good doctor – check out a couple of Tom Baker serials!) Be that as it may, Fred F. Sears does an acceptable job as director; Curt Siodmak supplies a clever screenplay based on Don Keyhoe’s book (Keyhoe also wrote ‘non-fiction’ accounts of UFOs); and some of the dialogue is definitely quotable! IMDb has some ripper examples.

Watch it and enjoy it. Strip some of our contemporary SF of CGI and they really do lack substance in comparison with this entertaining and funny movie. OK. You won’t gasp and ooooh. If you have a love of ’50s B-movies however, this one is a ‘corker’!”
