10. "It's not exactly a normal world, is it?": Batman didn't just make the superhero movie a lucrative option for Hollywood -- it was really the prototype for the pre-branded, pre-sold, pre-marketed modern blockbuster. Sure, Star Wars and Jaws created the "summer tentpole," but Batman was based on a pre-existing property -- and 25 years later, Hollywood is almost all about pre-existing properties. Rarely will a movie get the green light if it's not connected to a comic, a best seller, a TV show or an earlier film. The success of Batman also led to the acclaimed Batman: The Animated Series, which itself was the launching pad of the DC Animated Universe -- with the shared universe concept now consuming movie franchises at every turn. The world of film today may not be a normal one, but Batman played a major role in inventing it.
