Cancelled 'Justice League' film gets documentary

A documentary aimed to tell the the story behind George Miller's "Justice League: Mortal", which was cancelled in 2008, is underway.
It will be helmed by Australian director Ryan Unicomb, reported Aceshowbiz.
Back in 2007, Warner Bros hired Miller to direct a "Justice League" film, which would exist alongside Christopher Nolan's Batman films at the time.
Filming was scheduled to take place in Australia and a number of actors had signed up for the project. The film would have starred Armie Hammer as Batman, DJ Cotrona as Superman, Megan Gale as Wonder Woman, Adam Brody as The Flash, Common as Green Lantern, Santiago Cabrera as Aquaman, and Hugh Keays-Byrne as Martian Manhunter.

Due to multiple problems, the film was cancelled. Warner Bros decided to instead focus on individual films like "Green Lantern" and "Man of Steel".
Unicomb has teamed up with producers Aaron Cater and Steven Caldwell to develop a feature length documentary.

"I have always been fascinated with the project, which would be in the same vein as 2013's Jodorowsky's 'Dune' and this year's 'The Death of Superman Lives: What Happened?', about a Superman movie that Tim Burton was to direct in the 1990s," he explained.
The producers also eye writer/author Maria Lewis to help develop the documentary. The plan is to interview some of the cast and crew who would have worked on the film.

They also plan to show never-before-seen artwork and costumes. The release date of the documentary has not been announced until now.
