Superman Fact

The original comic book Superman could leap tall buildings in a single bound, but then he had to come back down to Earth, because he did not fly. It was not until the 1940s, when animators for a new animated series decided it would be too difficult to routinely draw him bending his knees, that it was decided that Superman could take off into the air. Readers were able to see smooth animation, and a superhero gained a new power.
