Warner Brothers produced this two minute short to celebrate the seventy-fifth anniversary of Superman; he flies out of Action Comics #1 and we watch as he slowly changes: the Fleischer Cartoon version, the innumerable add-ons in the 1950s, from Supergirl to Super-Dog to Super-Goldfish to Mister Mxyzptlk (actually introduced in 1944), to his reinvention as George Reeves. Then we get his revival and restoration in the 1970s movie version and graphic novels....
It's a puff piece, but it makes the real point that Superman has changed, as all mythic figures must in order to remain constant. In mythographic terms, the sign remains constant, but what it points to changes.
Happy 75th Birthday, Kal-El.
