Frank Miller took to the stage at Brazil's CCXP comic book show, to be interviewed. And we learnt a few things, some we knew, some we didn't.

So while he again affirmed that Brian Azzarello is the actual writer of Dark Knight 3: The Master Race, he told us about a project he would like to create similar to the Dark Knight but focused on Superman. But a story in which Batman. Bruce Wayne, is the bad guy.

Could this be Dark Knight 4? Or something completely different?

He also talked more about his next planned Sin City comic which he told Le Monde would be called Home Front. It may have changed to something a little more literal since, namely Sin City 1945, with a secret agent fighting against Nazis.
