I read the original books, they were great sci-fi.
The movie did not do them justice, kinda campy even for their time.
Of all the sci-fi movies of the 50’s this one needs a modern remake.................
Perhaps their movie failure changed minds on filming
the sequel. Don’t believe it was ever made. Read both
books back in the 50/60s. What would the world be with
no moonlight? AWC was encouraging- at least they had
heat thanks to a ‘stowaway’. Had to search diligently for
the book sequel before it was found.
