Syfy's Krypton has cast six more roles ahead of its planned 2017 debut, according to Deadline. If accurate, this sextet would join Cameron Cuffe and Georgina Campbell, playing Seg-El and Lyta Zod, respectively.
Ian McElhinney (Game of Thrones) will reportedly play Val-El, grandfather to Seg-El (and therefore great-great-grandfather to Superman). The Hollywood trade describes him as "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 said to play the Chief Magistrate of Kandor, Daron Vex. "His real business is defending Krypton’s established oligarchy against heretics and dissidents," describes Deadline.
Wallis Day (The Royals) will play the daughter of Cowan's Daron Vez, Nyss Vez.
Ann Ogbomo (World War Z) reportedly has been cast as Primus Alura Zod, mother to Campbell's Lyta Zod. She is the leader of the Kryptonian military guild.
Aaron Pierre (Tennison) is playing a cadet serving under Alura Zod.
Rasmus Hardiker (Your Highness) is said to play Seg-El's best friend, "a brilliant engineer" who is a "partner in an underground tech-repair business."
Krypton is set two generations before the onset of Warner Bros.'s Man of Steel, following Superman's grandfather - played by Cuffe - and Zod's grandmother - played by Campbell.
