Mark Millar has done some big things at Marvel. Civil War, Old Man Logan and even Ultimates have all been big successes for Millar and Marvel. Bleeding Cool reported on Millar's posting at his Millarworld forums:
Apparently Millar is scheduled to meet with Joe Quesada about this today. It sounds as if Millar is pumping this up himself. But if he's that confident in his idea, why not? That kind of enthusiasm is what all writers should have. Who wants to hear a writer say they're going to do something that will turn out "okay." The real question is, what could this "family car" be that he wants to borrow?
I’m basically wanting to borrow the family car for a little while, take it on the scariest ride ever and hopefully hand it back in one piece.
Hopefully the fact that this has the potential to be bigger than Civil War will convince him. Here’s hoping as I love this. I just have that crazy good feeling about it when you know you’re onto something big. I knew we had it with Old Man Logan, Kick-Ass and Ultimates and I smell it here. This has the potential to be absolutely crazy.
