Production is getting ready to move forward on Gunn's first Superman movie for the DC Universe, especially with David Corenswet now officially set to take over the role of Clark Kent.
He'll become one of nearly a dozen actors who have taken on DC's most iconic superhero, giving fans a much different take on the Kryptonian native in the reboot that will immediately follow up on Cavill's Superman.
The Hollywood Reporter shared new details on how James Gunn's story in Superman: Legacy will be different from the one told in Henry Cavill's Man of Steel, the first movie in the DC Extended Universe directed by Zack Snyder.
In Superman: Legacy, Superman will be "joining a world in which superheroes already exist" rather than the way Cavill was the only superhero, that the audience knew of, in his own universe during Man of Steel (other than the other Kryptonians that came to Earth).
This was later confirmed by several superhero castings for Superman: Legacy, with Hawkgirl, Guy Gardner's Green Lantern, Mr. Terrific, and the elemental Metamorpho all already existing in the universe.
James Gunn has since justified the story decision to include other superheroes on Instagram.
