Can Green Lantern be DC's Iron Man and set the stage for a Justice League team movie to compete with The Avengers? Warner Brothers Motion Picture Group President Jeffrey Robinov hopes so. Robinov plans for GL, Batman, Superman, Wonder Woman, and Flash to help pave the way for a Justice League movie in 2013 and sustain billions in revenue Warner Brothers stands to lose when the Harry Potter series wraps up, a recent interview indicates. It looks like the fate of the whole Justice League may be riding on GL's box office battle.
