Now it's on his website, so it seems worth bringing up. “Sure. I mean, (being asked to write a Superman movie) would never happen. So it’s really easy for me to say ‘Yes.’ But sure. That’d be interesting. I’d take a swing at something like that. I don’t know what my story would be. Actually, that’s not true. I know exactly what my story would be. But I can’t give it away. It’s the one Superman story I’ve got in my back pocket that -- if we all live long enough -- maybe someone will ask me to tell it someday.” I think we can all agree that, especially with Johns off the big boys' table, this won't be happening as anything other than hopefully a comic down the line. But would it have been a positive prospect under any circumstances?
I'd say it's relevant he has experience working with a version of Superman built on foundations he's not fond of - the post-Byrne, post-Phantom Zoner execution Superman is who he was writing in his JLA run - and while he expressed some discomfort with earlier parts, my impression is that he enjoyed Man of Steel up until killing Zod, rather than that being the straw that broke the camel's back. And while his average quality's dropped precipitously in recent years, he generally can still bring it for one or two projects at a time, and it's hard not to imagine him giving this the bulk of his attention.
