Justice League Mortal was to be a film directed by George Miller and starring Megan Gale as Wonder Woman, Armie Hammer as Batman, D.J. Cotrona as Superman, Adam Brody as the Flash, Common as Green Lantern and Santagio Cabrera as Aquaman.
A lot of light has been shed unto the film with the leak of the script onto the internet, however, it was the CV or portfolio of artist, Johnathan Gwyn, that revealed a little known fact about the film, a tie in game was well into development. The game was to have been developed by Double Helix (the company who made the Green Lantern movie tie-in video game). Development continued even after the main project had been shut down, but as a general Justice League title.
To date, no known prototypes or demos of the game have been sold or released to the public.
