In 1967, Hanna-Barbera supplied CBS with three more superhero series. The Herculoids was set on a distant jungle world. Herman Melville's Moby Dick was rebooted as a heroic whale helping a pair of boys on some undersea adventures, and shared a half-hour with Mightor, a Stone Age superhero whose debut predated the campier Captain Caveman by a full decade. Finally, there was Shazzan, a towering genie at the service of a pair of New England teens who were transported through time to the days of the Arabian Nights. Cosminmq uploaded the open, which also includes a short introduction to the storyline, to YouTube:
Sadly, production was halted on the series before Chuck & Nancy (voiced by Jerry Dexter & Janet Waldo) could deliver the two-part ring to its rightful owner. Only one season's worth of episodes was produced, and continued to air for at least a 2nd season.
Hanna-Barbera would revisit ancient Baghdad again the very next season, with the Arabian Knights as a component of the Banana Splits Adventure Hour. However, Shazzan & the Knights would never meet, though logic suggests that, in the right hands, such a team-up could take place to bring closure to both series' storylines. Of course, the broken ring gimmick would also be used again, in 1979's horrid reboot of the Fantastic Four's strongman, The Thing.
