I know Brandon Routh is reprising his role as Kingdom Come Superman and Marc confirmed this is the Reeves/Routh version from Superman Return so this means all 5 of those movies are canon to the Arrowverse right?
Its also confusing since there are two versions of Superman II. I’ve always assumed that Superman Returns has to follow the original cut of Superman II, since Lois has his son in Superman Returns, and he wiped their brief relationship out of history in the Donner cut. Of course, he wiped her memory in the original version, which must have left her very confused when she became pregnant.
But Lois clearly doesn’t know that Clark is Superman, so she can’t remember any details of Superman II.
I guess the most likely explanation is that he did erase her memories of Superman II, either with a magic kiss or time travel, and then they hooked up again later.
The new episode of Crisis seems to indicate that Superman III and Superman Returns both take place in the same continuity. Clark mentioned his son Jason, and he also mentioned going crazy and fighting himself.
