Here's what Nolan had to say about the Superman film:
...he told me his take on it. I thought it was really tremendous. It was the first time I’ve been able to conceive of how you’d address Superman in a modern context I thought it was a really exciting idea.My biggest problem with Superman Returns was not the same as everyone else. A lot of people didn't like the movie because there was no action, or very little. I looked at it the same way Nolan and Goyer did; that there was no way to relate the character to today. A guy that wears red, blue and yellow tights? That stands for truth, justice and the American way? That doesn't happen anymore.
We're in a world where people literally blow themselves up to kill others. Superman CAN NOT stop that. A world where crimes are being committed by guys in suits, not guys with guns and knives. THAT is why Superman Returns didn't work (and a whole mess of other problems I wont get into).
I trust what Nolan says, and am excited to see what Goyer can bring to this mess of a table. I will keep a close eye on this and let everyone know what's happening. For now, we have to trust in our Godfather or superhero movies, Christopher Nolan.
