The production design of the film Fantastic Four: First Steps is an homage to the early ‘60s comics created by Stan Lee and Jack Kirby. While Kirby is best known for his bold, fist-popping drawing style, he was also a great storyteller who redefined what comic books could be. He was appreciated by hardcore fans at the time, but he never got the same media attention as Stan Lee and wasn't compensated for the fortunes his characters made. I talk with Kirby experts Charles Hatfield, Mark Evanier, Randolph Hoppe, and Arlen Schumer about where we can see Jack Kirby's influence on comics like The Fantastic Four, The Hulk, Thor, Captain America and Black Panther. And I explore Kirby's childhood at the Tenement Museum on the Lower East Side, where every day was “clobberin’ time,” and he first learned how to use a garbage can lid as a shield.
