A decade after Warner Bros. pulled the plug on the film, director George Miller's Justice League: Mortal came roaring back this week with a steady stream of never-before-scene production art, including a photo of D.J. Cotrono as Superman, and a costume test featuring the assembled superheroes. Now we can add to that concept art of the Man of Steel and the Dark Knight.
The images, which once again arrive courtesy of the fan site DC Films Hub, offer a more detailed look at the costume designs for the two iconic heroes. Of particular interest is Weta Workshop's approach to Batman's suit, made primarily of a composite mesh material that would have presumably allowed Armie Hammer to enjoy more freedom of movement than his big-screen predecessors. That extends to the cowl, suggesting this Dark Knight might've been able to actually turn his head onscreen.

The Superman design differs significantly from what we saw in the Cotrono test photo, in that it includes the hero's red trunks. However, the final product did retain the red field connecting the chest emblem to the cape.
In addition to Cotrono and Hammer, Justice League: Mortal was also intended to star Megan Gale as Wonder Woman, Adam Brody as The Flash, Santiago Caberera as Aquaman, Hugh Keays-Byrne as Martian Manhunter and Common as Green Lantern. They were joined by Jay Baruchel as Maxwell Lord, Teresa Palmer as Talia al Ghul and Anton Yelchin as Wally West.
Beginning development in the wake of Bryan Singer's 2006 film Superman Returns, Justice League: Mortal was shelved by Warner Bros. on the eve of production in January 2008, amid a writers strike, concerns about Australian tax incentives and the possibility of an actors strike. All of the primary roles were cast, costumes designed, and Weta had reportedly constructed at least some of the sets.
