As part of the crossover, Superman Returns’ Brandon Routh will return to play the Man of Steel again.
Kingdom Come is a tale of a dark future, where the DC superheroes are mostly retired.
The five-part “Crisis on Infinite Earths” crossover begins on December 8 on Supergirl and then continues on December 9’s Batwoman, December 10’s The Flash and then (after a Christmas break) on January 14’s Arrow and Legends of Tomorrow.
It makes sense to use Routh in this role within the series, as this Superman has jumped into other universes and series before. Plus, it’s a really great costume.
