A reign of terror begins as a vengeful, self-proclaimed “Mad Scientist” issues a chilling ultimatum to the city: stay out of his way, or face his powerful new weapon, the ‘Electrothanasia-Ray’. While the police are baffled, star reporter Lois Lane refuses to be intimidated.
Determined to get the scoop, she bravely flies to the scientist’s remote mountaintop laboratory. But her courage leads her straight into a trap, and she becomes a hostage. Now, with Lois as his captive audience, the scientist demonstrates his ray’s awesome power by destroying a massive bridge and taking aim at the Daily Planet building itself. Only one hero is powerful enough to intervene. This iconic, action-packed adventure makes “The Mad Scientist” the perfect premiere episode of the classic Fleischer Superman cartoons.
