There is a chance the Superman & Lois Lex Luthor will accomplish James Gunn's plans for the character first. Gunn is DC Studios' new creative chief. While Gunn has a new executive job, he will remain very much involved with the production of every new entry in the rebooted DC Universe, which will span movies, series, animation, and video games. In fact, Gunn will be actively spearheading some projects himself. Chief among those is 2025's Superman: Legacy, as Gunn is writing and directing the reboot movie of the Man of Steel, which sees Henry Cavill vacate the Superman role in favor of a younger actor taking on the coveted part.
