When this show aired, it upset so many people. The National Association of Broadcasters said: “An all-time low in bad taste, with the President of the United States in a Superman role. NBC was responsible for this direct ideological approach to totalitarianism. We fear that there may be other broadcasters who are irresponsible enough to keep it in circulation.”
The idea of a super-powered American President seems dumb, but four years after the death of Kennedy and as America seemed to be on the verge of falling apart, maybe it seemed like a great plot for a cartoon. At least the DePatie–Freleng studio, who also made The Pink Panther cartoons, were commissioned to make Warner Brothers specials and also animated the lightsabers for Star Wars, thought so.
The President of the United States, former astronaut James Norcross, is voiced by Paul Frees, whose voice has been in almost everything you’ve ever watched. Other voice talent included Ted Cassidy, June Foray and Don Messick, whose voices would be in the few things that Frees didn’t work on.
Super President got his powers from a cosmic storm, just like the Fantastic Four, giving him increased strength and the ability to change his molecular composition like Metamorpho, plus he has a cave and special vehicle called the Omnicar like Batman and his Batcave and Batmobile.
Perhaps this cartoon, while forgotten today, inspired Calvin Ellis, the Kryptonian President of the United States on Earth-23 who is also the Superman of that reality (and just happens to look like Barack Obama).
