A rare collaboration between Fleischer Studios and Ub Iwerks resulted in this cartoon, based on the moderately successful Republic Pictures "Zeppelin vs.
Pterodactyls" cliffhanger serials.
The cartoon was shelved for half a century due to a three way legal dispute between Republic, Fleischer and Iwerks.
The Academy of Motion Picture Arts and Sciences rejected Oscar nominations for Ben Burtt's sound design in the cartoon because it had not been formally released and because of the legal status.
Actually it's a mashup I made from the following old public domain cartoons: Superman - (self-titled episode) Superman - Arctic Giant Superman - Billion Dollar Limited Superman - The Bulleteers Superman - Japoteurs Superman - Jungle Drums Superman - Mechanical Monsters Superman - Terror on The Midway Superman - The Underground World Betty Boop - Ha Ha Ha!
