- Big-Lipped Alligator Moment: The weird bit with the ship's cats towards the end. The Moon Men insist the crew leave the two cats behind, so the crew takes the cats' cages outside. We see an ominous shadow fall over the poor kitties, and then...nothing. No mention is made of why the Moon Men wanted the cats (beyond finding them "interesting"), or the felines' ultimate fate.
- What Happened to the Mouse??: or cats, in this case.
- Fair for Its Day: For a movie made in 1954, the treatment of the Turkish, Nigerian and Soviet characters is pretty remarkable. The Turkish Muslim character is almost progressive by today's standards. Even though there's a lot of unfortunate implications with Hideko it is pretty amazing that she gets a lot more screen time than the film's single caucasian woman and this was 1954.
- Magical Asian: Hideko has an intuitive understanding of alien languages because she's Japanese for some reason.
- Narm: The bravery of David and Heinrich's Heroic Sacrifice is significantly undercut by the fact that David appears to be sitting in Heinrich's lap the entire time.
- Special Effects Failure: The
Corn Popsasteroid field. Also when Heinrich and David's ship crashes.
- The lights in the ceiling of the moon set are visible in a couple of shots. Probably wouldn't be visible when shown in widescreen, though.
- Strangled by the Red String: Sigrid and Selim's attraction pretty much comes out of nowhere.
