It's possible as a Justice League movie is trying its hardest to get to cinema, directed by George Miller, or are these from DC Universe Online?
The shots, as reported by Kotaku, are taken from an ex-Shiny Entertainment artist’s online portfolio. The studio is known for its movie-tie videogame projects (The Golden Compass and The Matrix: Path of Neo).
They're part of Double Helix who have signed for a Green Lantern videogame, based off the upcoming Warner flick. Logos for Justice League big wigs are in the shots like Superman, Aquaman and Wonder Woman. Are these real, or from DC Universe Online?
