7/ The final approval sheet from DC Editorial also shows Mike Carlin, Archie Goodwin, and Dennis O'Neil's thoughts. Carlin writes that "Mark is so way off in his understanding of [Superman] that it will help make this title a very different Superman." If anyone can help decode O'Neil...

6/ Hal Jordan is mentioned, and editor Mike McAvennie asks Millar to make the story more concise and "neat." Mark also says he enjoys Superman, but I find it hilarious that the editor told him he doesn't understand the character.
He also requests Watchmen's Dave Gibbons & Mike Mignola to draw it.

5/ Millar calls Superman a totalitarian and said that he had no doubts about "Superman believing what he believes to he law and order" and that this "strict behavior would be very much in character." Also discusses his version of this "grimmer and tougher" than ever.

4/ Mark also said that in a universe where Superman didn't exist in Metropolis that Lex Luthor would be looked at as a hero. Man of Steel is mentioned:

3/ In the first letter of the pitch, Mark talks about the original desire to see Superman "not believing in the American way and also instilling the rights of the common worker" with a crumbling US by the hands of Cuban.
He also makes some wittingly poor grammatical errors in the email.

This edition has the entire original pitch made by Millar in the mid-90s along with the letter sent to DC editorial by then-Superman editor by Mike McAvennie. It seems as though the series was supposed to be four to six issues long instead of the ending three issues it had been.
