Re: Superman (casting, rumors, pix till release)
If reports I've seen are true Chris did a couple of re-writes of the script last summer (just before filming started on The Dark Knight Rises) when it was having problems. This was before Kurt Johnstad was brought up to do touch ups. Jonah Nolan co-wrote it with David Goyer I believe. As far as the directing has gone, I think Nolan has been quoted as that is all Synder, Zack has free reign where that is concerned.
