Jerry Siegel: "I loved The Mark of Zorro, and I'm sure that had some influence on me." ..."When writing the script, I had Douglass Fairbanks very much in mind in the athletic stunts that he did too, so the influence of Douglass Fairbanks was not only in the art but in the visual action."
Joe Shuster - "I was a great fan of Douglas Fairbanks, and so was Jerry and I tried to use his stance, the way Douglass Fairbanks looked, ...with his hands on his hips, in Robin Hood and Mark of Zorro, in all those he had those marvelous attitude..." " [His costume] was inspired by the costume pictures that Fairbanks did: they greatly influenced us. He did The Mark of Zorro, and Robin Hood, and a marvelous one called The Black Pirate - Fairbanks would swing on ropes very much like Superman flying... the feeling of action as he was flying or jumping or leaping - a flowing cape would give it movement.
Bill Finger - "Batman was a combination of Douglas Fairbanks [who played Zorro] and Sherlock Holmes."
Bob Kane -"Zorro’s use of a mask to conceal his identity as Don Diego gave me the idea of giving Batman a secret identity…Bruce Wayne would be a man of means who put on a façade of being effete. Zorro rode a black horse called Tornado and would enter a cave and exit from a grandfather clock in the living room. The bat-cave was inspired by this cave in Zorro. I didn't want Batman to be a Superhero with superpowers…So I made Batman an ordinary human being; he is just an athlete who has the physical prowess of Douglas Fairbanks, Sr., who was my all-time favorite hero in the movies.”
