Re: How to avoid rehashing elements from the Nolan Trilogy
Even if the Batman reboot doesn't redo the origin, two of the things it will most definitely have because of MOS is a young Batman early in his career and an establishment of all the messages & themes that are true about Batman that BB already covered - what makes him who he is, why he uses fear against criminals, etc. Even without redoing the origin, you still risk rehashing a lot of of things from Batman Begins and The Dark Knight.
For the record, we don't know how similar Man of Steel will be to the TDK trilogy. We are purely trying to get an idea of how similar they are based on what we've seen so far of it, on what the production crew said, and on what those who said the early screenings said. So far, MOS looks very similar to what Nolan did with Batman. The film itself being described as a "Nolan story" is a big thing right there.
One way I think they can avoid this is by putting emphasis on what a brilliant detective Batman is and what a genius he is overall, which is something that Nolan didn't do. Nolan put more emphasis on Batman's martial arts and tech. Establishing from the beginning that Bruce is a modern Sherlock Holmes would already be something big that differentiates it from the Nolan films. Another thing that will help would be a different and more theatrical looking costume. Even the white eyes being there would go a long way.
