The search for the DC Universe’s Superman continues, and according to some reports, it all points to James Gunn possibly continuing a major Superman change in Superman: Legacy that began when Zack Snyder cast Henry Cavill. Superman was the hero that kicked off the DCEU, but unfortunately, this universe didn’t give him a consistent story after his debut in Man of Steel. After Man of Steel 2 was announced to be in development, these plans changed with the introduction of the DC Universe, which will have a younger version of Superman, thus leaving Henry Cavill’s version out of this new branch.
