Trivia
The tubing on the side of the adult Martian helmets is a natural gas line, similar to the type used to hook up a water heater or furnace.
When Santa begins making toys, one Martian is fascinated by "a coiled spring that walks down stairs". Slinky had a resurgence in the early 1960s.
A new audience discovered this film when it was critiqued on Mystery Science Theater 3000 (1988).
This film is listed among The 100 Most Amusingly Bad Movies Ever Made in Golden Raspberry Award founder John Wilson's book The Official Razzie® Movie Guide.
The film is included in "The Fifty Worst Films of All Time (and How They Got That Way)" by Harry Medved and Randy Lowell.
Stobo, portrayed by Al Nesor, is often thought to be Jamie Farr instead.
Voldar and Kimar's rivalry could be a subtle reference to Edgar Rice Burroughs' John Carter of Mars series. Voldar has green skin, and Kimar has red-tinted skin. In the book, the green and red martians were fierce rivals stricken by interciene warfare.
