'Krypton' Superman TV Prequel On Syfy: Main Cast Is Complete With 'Game Of Thrones' Actor - Everything To Know

Syfy is preparing a TV prequel on the life of Superman's family. The show, entitled "Krypton," has already picked its principal cast members, which will include a former "Game of Thrones" actor. Here's everything a fan of the superhero and the "Superman" mythology should know about the upcoming television show.

"Krypton" on Syfy will take place decades before the destruction of Superman's planet. The show's main focus will be on Seg-El, who is known in the DC Comics series as Superman's ancestor.

Playing Seg-El on "Krypton" is Cameron Cuffe, who is a theater actor from London, reports Deadline. His character is described as someone brilliant with technology and the House of El on "Krypton" used to be a powerful family on the planet. But because of a crucial incident, Seg-El and the rest of his family have been ostracized by high society and downgraded to the lowest caste.

Joining Cameron Cuffe is Georgina Campbell as Seg-el's love interest Lyta Zod. She belongs to a high profile military family on "Krypton" and their relationship is being kept a secret.

Also in the cast of "Krypton" are Aaron Pierre, Elliot Cowan, Rasmus Hardiker Ann Ogbomo and Wallis Day. "Game of Thrones" actor Ian McElhinney also has a crucial role as Val-El, Seg-El's grandfather. TV Line reports that his character is a space exploration expert who knows that something is up with the planet Krypton.
