"In the endless reaches of the universe, there once existed a planet known as Krypton, a planet that burned like a green star in the distant heavens. There, civilization was far advanced, and it brought forth a race of supermen, whose mental and physical powers were developed to the absolute peak of human perfection. But there came a day when giant quakes threatened to destroy Krypton forever. One of the planet's leading scientists, sensing the approach of doom, placed his infant son in a small rocket ship and sent it hurtling in the direction of Earth, just as Krypton exploded. The rocket sped through star-studded space, landing safely on Earth with its precious burden: Krypton's sole survivor. A passing motorist found the uninjured child and took it to an orphanage. As the years went by and the child grew to maturity, he found himself possessed of amazing physical powers. Faster than a speeding bullet, more powerful than a locomotive, able to leap tall buildings in a single bound, the infant of Krypton is now the Man of Steel: SUPERMAN! To best be in a position to use his powers in a never-ending battle for truth and justice, Superman has assumed the disguise of Clark Kent, mild-mannered reporter for a great metropolitan newspaper."The Mad Scientist note is a 1941 theatrical cartoon produced by Fleischer Studios, and the first of the Superman Theatrical Cartoons.The short was nominated for the 1942 Academy Award for cartoon short subjects (losing out to the Pluto The Pup short Lend A Paw) and has earned a position on no. 33 on The 50 Greatest Cartoons.This short has slipped into the Public Domain, and can be viewed here.
