A four dimension film? Well you can't say that Nolan has become complacent in his post Dark Knight career. The opening shot of Paris folding in on itself could have confirmed that, but the question will be how will the film perform with its large budget.“It’s something that we had been talking about on and off for seven or eight years," Thomas said. "Coming off of the ‘The Dark Knight,’ the only thing we really knew is that we wanted to do something more personal. It seemed like the right time to do this. The fact that it’s really just an enormous movie -- that wasn’t ever really a factor in the decision. This story lends itself to a movie of this size."
