The story is very cartoony, Bug Bunny cartoony, with bad guys who use obvious disguises. They get blown to smithereens yet somehow are only incapacitated.
The Adventures of Superpup isn’t the cartoon about Superman’s dog Krypto. It’s a live-action children’s show about Superman except with dogs as the main characters.
The actors are little people in animal costumes. Costumes they can’t see out of! In one scene, the villain Professor Sheepdip can be seen visibly feeling around for the door knob right in front of him.
The series never got green-lighted but the pilot was released on the 14-disc Ultimate Superman Collection DVD set. It includes the documentary You Will Believe: The Cinematic Saga of Superman. There are great insights into the Superman franchise including an anecdote about Marlon Brando wanting to play Superman’s father Jor-El as a bagel. Not a talking bagel, just a plain bagel. And you thought Superpup was out of this world.
