Trivia

The thawed out Tyrannosaurus was the inspiration for Godzilla.

In this short (as in some of the others) Superman leaps from place to place (like later Marvel's Incredible Hulk), rather than flying. This is from the original comics version, in which he didn't fly either. He was given the ability to fly, in the comics as well as the animated series when the creators realized that what looked good in heroic static drawings made him look like a red-and-blue kangaroo bouncing over buildings.

The museum depicted is likely based on the American Natural History Museum in New York City. The famous institution has made cameo roles in several films, cartoons and TV productions over the generations.
