Back in 2007, Warner Bros began planning to release Justice League: Mortal in 2009 release, but at the beginning of 2008, the movie was cancelled due to the Writers Guild strike and other production obstacles.

Actor D.J. Cotrona, who was initially set to play Superman in the movie, told Slash Film that fans missed out on seeing director George Miller’s gigantic interpretation, citing this year’s Mad Max: Fury Road as proof of what he could have accomplished with the DC heroes.

“The best way I can describe it is: George Miller’s mind is so operatic and big and expansive, it’s a shame that the world didn’t get to see what he would do with superheroes,” said Cotrona.

“It was allegorical, like a story of Greek Gods almost … he was doing things with the Superman and Batman characters, and all the iconic favorites, that’s never been done before. Watch Fury Road and you can only imagine what he would do with those iconic characters.”

Miller’s next project, however, is Mad Max: The Wasteland, but had Justice League: Mortal moved forward as planned, DC fans would have seen – apart from Cotrona as Superman – Armie Hammher as Batman, Megan Gale as Wonder Woman, Adam Brody as The Flash, Common as Green Lantern, Santiago Cabrera as Aquaman, Hugh Keays-Byrne as Martian Manhunter, Jay Baruchel as Maxwell Lord, and Teresa Palmer as Talia Al Ghul.

Meanwhile, a documentary from Australian director Ryan Unicomb is being planned to explore the abandoned film in the same vein as the recent The Death of Superman Lives: What Happened?.

Unicomb promises to feature interviews with the cast and crew, concept art, and even a few costumes. Justice League: Part One, though, hits theatres on 17 November 2017, with Justice League: Part Two following on 14 June 2019.
