A few years back, George Miller, the director of the "Mad Max" film franchise, had some plans for a "Justice League" movie, which was titled "Justice League: Mortal." Unfortunately, the project was scrapped and no one knows what happened to it.

But now, it seems like things are starting to be uncovered, as many details from that project have been emerging, as what io9 reported last June when concept arts for "Justice League: Mortal" were posted online.

Recent news suggest, however, that a documentary for the scrapped project is currently being planned and is simply awaiting Warner Bros' approval.

While talking to If Australia, director of the "Justice League Documentary," Peter Unicomb, said, "It's a nervous wait. George Miller and Doug Mitchell know about the project, so now it all hangs on Warner Bros' involvement."

Unicomb has explained that the production or the documentary rather, aims "to celebrate the genius of George Miller and the amazing artists who worked tirelessly to bring the production's vision to fruition, while we also examine the cultural immortality of the Justice League characters across all forms of media."

There is no word yet from Warner Bros. though, but if this projects gets the green light, Unicomb plans to interview the people behind "Justice League: Mortal," from the director and producers to artists who used to worked on the project and the actors who were supposed to appear in the movie as superheroes.

While waiting for WB's approval, fans, for now, can look forward to the new "Justice League" project which is directed by "Batman V Superman: Dawn of Justice's" Zack Snyder, dubbed as "Justice League Part One."

This new film project has been given a release date and is slated to premiere in cinemas on November 2017. The "Justice League Part Two" will be released in cinemas two years later on June 2019, as reported on IF.
