Well here is a nice find the boys over at Batman-News dug up. Seems that Dwayne Johnson hinted at the John Stewart Green Lantern role back in November, when he posted that very image you see above on Instagram with the hashtag #JohnStewartCanStillWhupSupermansAss. I don’t think many people saw that, because the rumor of him taking the green suit all came out of speculation. Johnson met with Warner Bros. and DC not too long ago, so the internet world blew up with what roles he could possibly play. Obviously since they are not going to bring back Reynolds as Hal Jordan (even though they should) the John Stewart Green Lantern fits Johnson’s look, so everyone is thinking it will be him.
As much as he would fit as the Green Lantern, I honestly would rather have him play a villain. Just because he is always the hero, and I want to see an evil Dwayne Johnson. He could still be misleading us with that Instagram post, but if he does end up being the Green Lantern, he will most likely make a small appearance in Batman Vs. Superman, and then of course that movie leading into the Justice League. Any more info and I will let you know.
