One of the first names we heard associated with Man of Steel was producer Christopher Nolan, who was described as a "mentor" for this highly-anticipated project back in February 2010. The news got fanboys worldwide excited, due to the massive success of his Batman blockbuster The Dark Knight. Today, the producer revealed that this Superman project is a much greater undertaking that his Batman trilogy, while praising director Zack Snyder's work at the helm.

"Zack was the perfect man to take this on. He is unbelievably skilled at creating a coherent, cohesive world -- whether it's a very stylized world, like 300, or something that's more challenging, more varied, like he did with Watchmen. In my honest appraisal, taking on Superman and creating that world is far more difficult than creating the world of The Dark Knight. He has a lot of finishing to do on the movie -- it has a very long post-production schedule because, unlike Batman, Superman flies."

The filmmaker also joked that he feels guilty talking about Man of Steel, since he has, "nothing to do."

"I actually feel guilty talking about it because I'm sitting here having nothing to do to it. I try to be as supportive as I can, and I'm just amazed by what he is doing. It's not something I would know how to do."
