Mogo's owner, Arthur Harris, gets blamed for a theft after Mogo creates a distraction at the circus...
...but Harris wasn't responsible!
Batman and Robin go to clear Harris' name and Mogo tags along.
As Harris is cleared, he takes Mogo back to Africa and sets him free (and later appears on an episode of the animated Batman: Brave & the Bold series).
Sounds almost like an episode of the 1960s Batman TV show produced by 20th Century Fox...no?
Planet of the Apes on Batman
Maurice Evans played the Puzzler (a Riddler-knock off when Frank Gorshin wasn't available) in two episodes of Batman, ("The Duo Is Slumming" and "The Puzzles Are Coming") in Season 2 in December, 1966...and was Dr. Zaius in Planet of the Apes (1968) and Beneath the Planet of the Apes (1970).
Don't blink or you'll miss her in the 2001 Planet of the Apes....or in the Batman episodes!
"Fat Man" was a reference to the bomb, as the mutants worshiped the atomic bomb...and maybe to his other qualities as well.
Wynant is likely best remembered from his time in the Twilight Zone, in the episode "The Howling Man" from 1960!
