Last year we got a peek at concept art for Justice League: Mortal, the project that George Miller was slated to direct back in 2007. Our own Chris Clow provided a very detailed account of the project nearly three years ago, pointing out that Miller had been "relatively silent" about his role in the production.

Miller, who has now been nominated for two Academy Awards for his work as producer and director of Mad Max: Fury Road, recently sat down with The Hollywood Reporter to discuss some of his career highlights. He also touched on the superhero project that, sadly, never took flight.

"There was a really great script. And Warners said, 'Let's do it. Let's do a Justice League.' I really was attracted to it. But there was a writers strike looming. We had to cast it very quickly, which we did with Warners' casting people. And we cast it really quickly and we mounted it very quickly. And it depended on a start date and it depended on some basic rebate legislation that had just got through a new Australian government.

"But it was just too big a decision for them to make in the time. And that fell through and the whole film fell through. We almost got there. And it wasn't to be. But that happens a lot, where films line up and the stars look like they're aligning and they didn't."

The cast would have included D.J. Cotrona as Superman, Armie Hammer as Batman, Megan Gale as Wonder Woman, Adam Brody as the Flash, Common as Green Lantern (John Stewart), Santiago Cabrera as Aquaman and Hugh Keays-Byrne as the Martian Manhunter.

The idea was that Justice League: Mortal would have existed alongside Christopher Nolan's Batman series (The Dark Knight came out in 2008) and the Superman series rebooted by Bryan Singer in 2006 with Superman Returns. But the plug was pulled before The Dark Knight became a huge success.

Who knows how things would have turned out with Justice League: Mortal. On the positive side, things are definitely looking up for the DC movie universe since Zack Snyder's Man of Steel in 2013. Batman v Superman: Dawn of Justice hits theater on March 25, followed by Suicide Squad on August 5. Next year brings Wonder Woman on June 23 and then, finally, Justice League Part One on November 17. 

Miller, meanwhile, turned his attention to the animated sequel Happy Feet 2 and, four years later, reaped huge critical acclaim for his superior action picture Mad Max: Fury Road, which made everyone happy and is now available on home video.
