Mostly, he talked about how the film will stay true to The Dark Knight's naturalism.
"The work we did was to bring the same naturalism as the Batman trilogy. Our approach has always been a naturalist, realistic, approach. We always try to imagine these stories as if they could happen in the same world in which we live. It is not an easy thing with Superman, and this does not necessarily mean that it will be a dark film. But in working on this reboot, we are thinking about what would happen if a story like this really happened. How would people react? What consequences would there be? What I like to do are stories set in "genres", parts of "gender", which, however, are not cartoons, or comics. I did the same thing with Da Vinci's Demons, and I did the same with Man of Steel.
Let's say that every time I work on a piece of fiction, whether it's Superman, Call of Duty, Da Vinci's Demons, I try to understand what issues are going on in the world, and I try to reflect on that, in all of my current projects. That said, when we wrote The Dark Knight, the Occupy movement was not there yet. Let's say that we have "predicted" that there would be very popular discontent, and we thought it would be a good opportunity to generate additional reflections related to this story. Working on relevant elements from the point of view of society can only make things more interesting ...
