“More and more, storytelling has become the art of world building,” writes Henry Jenkins in Convergence Culture: Where Old and New Media Collide. “The world is bigger than the film, bigger even than the franchise – since fan speculations and elaborations that also expand the world in a variety of directions.” As one screenwriter recently commented: “When I first started you would pitch a story because, without a good story, you didn’t really have a film. Later, once sequels started to take off, you pitched a character because a good character could support multiple stories. And now you pitch a world, because a world can support multiple characters and multiple stories across multiple media.”
