Superman (1941)

Synopsis
Directed by Dave Fleischer, brother of the legendary Max Fleischer (who serves as producer), this animated short film was the first cinematic adaptation of the classic comic book Superman. Long before George Reeves or Christopher Reeve donned the famous red cape, voice-artist Bud Collyer was Superman, providing the superhero's dialogue in dozens of shorts and television programs over the course of three decades. In this first adventure, Clark Kent must turn into his alter-ego Superman and save the people of Metropolis from certain doom at the hands of a maniacal scientist with a deadly energy cannon. Joan Alexander provides the voice of Lois Lane. ~ Matthew Tobey, All Movie Guide
