He is playing very coy, but we know that The Rock has spoken with DC about starring in their burgeoning cinematic universe. But is he hinting at who he might be playing?
Well known for his Twitter and Instagram accounts, Johnson recently posted an image of himself with producer Hiram Garcia. In amongst all this was the hashtag #JohnStewartCanStillWhupSupermansAss.
So could Dwayne Johnson be set to be a Green Lantern? John Stewart is one of several Earth based Green Lanterns, starting off as a backup to Hal Jordan. He features prominently in the animated series Justice League, becoming a founding member of the superhero team in that continuity.
Hopefully with the filming of Batman vs. Superman (or whatever it ends up being called) starting soon, with rumoured back to back filming of a Justice League feature, we will know sooner rather than later.
Batman vs. Superman is set for release in May 2016 with a cast that includes Henry Cavill (Superman), Ben Affleck (Batman), Gal Gadot (Wonder Woman), Jesse Eisenberg (Lex Luthor), Amy Adams (Lois Lane), Diane Lane (Martha Kent), Laurence Fishburne (Perry White) and Jeremy Irons (Alfred Pennyworth).
