The good news is that, I think, that Batman script is out. The bad news is, I think, they canceled it to make way for this film.
[Warner Brothers executives are] absolutely furious at Aint It Cool News' review of the script and [the studio] is complete panic mode. Heads are rolling and the entire studio is in turmoil. It seems they are scared to death they may have another BATMAN & ROBIN situation on their hands (they do) where negative buzz kills the film before it is even released. This time before it is even shot! The entire project is now in jeopardy and that they may have to throw out the entire script and start over.Someone who HATED the script and fought against it is the one who leaked it. But basically, there are a few people in the company who understand how bad the script is and that it will be a disaster the likes of which the company has never seen. We're talking a "CUTTHROAT ISLAND" sized bomb.
The Aint It Cool News review is 100% correct.
By the way, the studio heads, many of them have never seen the Donner film and do not know ANYTHING about the origins of SUPERMAN, which explains why they loved the Luthor is an alien concept.
