Mars and Beyond was a Walt Disney Space series from 1957. It discussed the planet Mars in a documentary format. It took time to talk about fictionalized versions of Mars, particularly Edgar Rice Burroughs variation of this world. It even (possibly inadvertently) created its own non-canon things in the context of Burroughs' Barsoom.
