It just got a big one too, with the female lead of the show now being cast. As reported by Deadline, Georgina Campbell has been cast as Lyta Zod. They explain the role as:
Lyta Zod is a member of Krypton's military caste and the daughter of a general, Alura Zod. Lyta Zod serves as a cadet — and has also been having a clandestine, forbidden romance with Seg-El. [Superman's Grandfather and the show's lead]
It feels like this show has been in preproduction for such a very long time now, so it is at least nice to see it making concrete headway. Here's hoping this pretty ambitious concept can be pulled off.
