Before the announcement of any DC slate of films, DC’s movie house had plans for George Miller to direct his adaptation for a Justice League movie. The cast was announced, script written, and concept art was designed… but nothing happened, no movie was made and the project fell Part. During a recent interview with THR, Miller explained what had happened
“Justice League was the main one. That was, oh, seven years ago, I think. And 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 Warner’s 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 wasnt to be. But that happens a lot, where films line up and the stars look like theyre aligning and they didn’t”
The film would have starred Armie Hammer as the Dark Knight, DJ Cotrona as Superman, Megan Gale as Wonder Woman, Adam Brody as The Flash, Common as Green Lantern, Santiago Cabrera as Aquaman, Hugh Keays-Byrne as Martian Manhunter, and Jay Baruchel as the villain Maxwell Lord, among other characters.
