As far I believe, these images posted by Hollywood stuntman and fight choreographer, Greg Van Borssum, are the first behind-the-scenes look at George Miller'scast. You can see: Armie Hammer ("The Lone Ranger") who would've played Batman, Adam Brody ("The O.C.") who would've been The Flash, D.J. Cotrona ("G.I. Joe: Retaliation") who would've played Superman, Megan Gale ("Project Runway Australia") who would've played Wonder Woman, Santiago Cabrera ("Heroes") who would've played Aquaman, Hugh Keays-Byrne ("Mad Max: Fury Road") who would've played The Martian Manhunter, Teresa Palmer ("The Grudge 2") who would've played Talia Al Ghul and Jay Baruchel ("Goon") who would've played Maxwell Lord. Only main cast members not included in the images below are Common (John Stewart), Anton Yelchin (Wally West), Zoe Kazan (Iris West) and Stephen Tobolowsky (Alfred Pennyworth).In February of 2007, Warner Bros. hired Keiran and Michelle Mulroney to write a script for a Justice League movie. This caught many observers by surprise as WB had just released Bryan Singer's Superman Returns the year before, and Chris Nolan was just beginning production of The Dark Knight. Leaving many fans wondering if Brandon Routh or Christian Bale was part of the equation. In September of 2007, George Miller ("Mad Max") came on board as director and would later confirmed that his film would feature new interpretations of Superman and Batman.Warner Bros. fast tracked the film in hopes of avoiding the Writers Guild of America strike, and scheduled the film to begin filming in February 2008 in Australia. This is when the perfect storm happened. Recently-elected prime minister, Kevin Rudd, changed the tax rebate incentive program and then the writer's strike took place. With an estimated budget well over $200 million, and with no ability to make changes to the script, due to the strike, Warner Bros. had to pull the plug on the project. It also didn't help that fan backlash to the film was incredibly high, so anticipation for it was lukewarm at best.
