"In part [the slow development of DC Comics films is] because no one wants them to go wrong. So you really look at these things, both the size of the bet that the studios have to make, the complexity of making the films," says DC chief Paul Levitz. "You really look at it and you want a script that you absolutely believe in, the right talent camera behind the camera and the right talent in front of the camera and if it doesn't feel like it's all coming together you say, 'Okay, not yet.' And this has always really been the case. It took us almost ten years to make the first 'Batman' film in the Tim Burton cycle and then it took us about ten years to make the first one in the Chris Nolan cycle."
