Well, okay, we generally credit Showcase #4 and Barry Allen for kicking off the Silver Age in 1956. But obviously, nothing comes from nowhere, and I wonder how much the Martin and Lewis movie, Artists and Models, helped to bring awareness of the superhero genre creeping back in 1955. Jerry Lewis is Eugene Fullstack, an early comic nerd who spends a lot of the movie just reading piles of comics, especially the adventures of Bat Lady, a pulchritudinous spacey crimefighter, before actually meeting her, or at least the artist's model who dresses as her played by none other than Shirley MacLaine.
Eugene seemed to really favour a brand of superhero with a sci-fi twist as were becoming popular at the time (he probably also liked Martian Manhunter and Captain Comet, though no "real" superheroes are mentioned in the film). At night he dreams about a sci-fi superhero of his own creation, Vincent the Vulture, much to the chagrin of roommate Dean Martin in this proto-Ernie and Bert scene.
