The Magnetic Telescope

The Magnetic Telescope (1942) is the sixth of the seventeen animated Technicolor short films based upon the DC Comics character of Superman, originally created by Jerry Siegel & Joe Shuster.

The story runs for about eight minutes and covers Superman's adventures in saving the town from a comet drawn toward Earth by a magnetic telescope.

[1] The story begins with Clark Kent and Lois Lane, along with the entire town, observing a scientist's (who resembles Captain Marvel's nemesis Doctor Sivana) demonstration of his magnetic telescope.

Newspapers the next day report the disaster, and the police are shown arguing with the scientist, who claims the importance of his work is worth the risk to human lives.

As he nears the building, pieces of the comet destroy the road in front of them, and the cabby flees; Clark takes this opportunity to change clothes in the back of the car, becoming Superman.
