James Gunn's Man of Tomorrow is shaping up to have even more DC heroes in the mix as Aaron Pierre has signed on to the Superman sequel, following his leading role as Green Lantern John Stewart in the upcoming Lanterns streaming show.
This makes John Stewart's next appearance official (via Variety), and seemingly confirms that he'll be a full-fledged Green Lantern by the time Lanterns wraps up. The series follows Stewart as he trains to replace Hal Jordan as Earth's protector.
