!!Novels
* EnsembleDarkhorse:
** Japanese valet Kyto doesn't start out this way, but he avoids being an EthnicScrappy in the first book and earns the status in the sequel with the reveal that he's a proficient, well-educated foreign spy who had a BecomingTheMask epiphany.
** Marian Jackson, a tertiary character from from the second book, is better-liked than some of the main cast due to being a CloserToEarth NonProtagonistResolver who is repeatedly underestimated by the main characters.
* UnintentionalPeriodPiece: Hitler and Mussolini are casually mentioned as contemporary world leaders who are widely despised but aren't actively at war with many other nations at the time, giving the book a very 1930s vibe.

!!From the 1951 film:
* SugarWiki/HeartwarmingMoments: David and Joyce taking in the first breath on Zyra.
-->'''David:''' Best air I ever tasted!
* HilariousInHindsight: Watching Stanton stagger out of his wheelchair gives one an urge to say, [[Film/DrStrangelove "Mein Führer... I can valk!"]]
%% {{Narm}}: The announcer who tells the camp that they're running out of time. "We're behind schedule! Make it up! Hurry! Hurry!"
* SpecialEffectsFailure:
** The matte painting showing the flooded and destroyed New York City, especially since its destruction was depicted earlier with models.
** A string can be visible on the nose of the ship after they land on Zyra.
** The not entirely convincing matte painting of Zyra at the end of the movie was originally meant to be a preliminary sketch. Unfortunately due to time and money constraints the artist wasn't able to produce a better work in time to be filmed.
* UnintentionalPeriodPiece: The plates on which the Bronson bodies were discovered are being shipped to the United States. By flying boat. The film also features a mechanical computer.
