It’s Popeye showing his American spirit on the 4th of July.
This is the first episode of the Max Fleischer Superman series in 1941. I love the visual style.
Superman must stop a madman from destroying Manhattan with electronically controlled earthquakes.
A mad scientist creates a giant magnet that brings celestial bodies down from the sky. The police try to destroy it just as he is in the process of bringing down a comet. This causes the comet to spin out of control and threaten to destroy the earth! Superman comes to the rescue.
