Having secured its leads in Cameron Cuffe (Florence Foster Jenkins) as Seg-El and Georgina Campbell (After Hours) as Lyta Zod, Syfy has now rounded out the series regular cast for its upcoming Superman prequel pilot Krypton.

Ian McElhinney (Game of Thrones) is set to play Val-El, Seg-El’s grandfather, and “a rogue genius who believes that space exploration is a basic form of self-defense, and he has tried, without success, to warn the Kryptonian elite about the arrival of an ancient threat.”

Elliot Cowan (Da Vinci’s Demons) is playing Daron Vex, “the Chief Magistrate of Kandor. His real business is defending Krypton’s established oligarchy against heretics and dissidents.”

Ann Ogbomo (World War Z) will portray Primus Alura Zod, “Lyta Zod’s mother and a leader of Krypton’s military guild. She is an extremely tough and demanding training officer.”

Rasmus Hardiker (Your Highness) will play Kem, “a brilliant engineer as well as Seg-El’s best friend and partner in an underground tech-repair business”, with Wallis Day (The Royals) as Nyssa Vex, “a junior magistrate and the daughter of Daron Vex”, and Aaron Pierre (Tennison) as Dev-Em, “a cadet under the command of Primus Alura Zod”.

David S. Goyer (Man of Steel) has written the pilot for Krypton with Ian Goldberg (Once Upon a Time), while Colm McCarthy (Peaky Blinders) directs and Damian Kindler (Sleepy Hollow) serves as showrunner.
