In this episode, which is ostensibly about the Spanish comic Rin-Tin-Tin, I go allll over the place. (Sorry). I begin with the early history of theater among the Egyptians and then the Greeks, discuss their use of animals on-stage, proceed to the Romans (who loved having animals on-stage, my goodness!), briefly describe the use of animals on-stage leading up to vaudeville, then vaudeville, the dime novels with heroic animals, the early silent films with heroic animals (there are several I single out and describe their histories), the stars among the movie animals of the 1920s, the debut of Rin Tin Tin--who didn't save Warner Brothers studio all by himself, despite the Hollywood legend--Rin Tin Tin's popularity around the world, Celebrity Pulps, how and why a Spanish comics publisher decided to make a comic about the real-life adventures of Rin Tin Tin, why it was a runaway success, Rex the Wonder Dog (because of course), ideasplosions, the awesomeness of Jesus de Aragon's Los piratas del aire (1929), various Spanish comics that made adroit use of ideasplosions, the ideasplosions of Rin-Tin-Tin, and the influence of Rin-Tin-Tin on not just other comics but on Spanish science fiction.
