In honor of Superman's 75th anniversary this year (Action Comics #1 was published in June 1938), here's a nifty little animated short film from Bruce Timm and Zack Snyder chronicling the Man of Steel's journey from comics to TV and film. Timm is the creative mastermind behind recent animated versions of Batman, Superman, and other heroes from the DC pantheon, both on television and in direct-to-DVD releases. Snyder is the director of the recently released Man of Steel movie. Notice how the drawing style changes to reflect Superman's evolution over the decades.
