Inhumans follows the royal family of the superpowered Inhuman civilization: Black Bolt the king, Medusa the queen, and Maximus, Black Bolt’s scheming brother. Fans who know Iwan Rheon from his role as Ramsay Bolton may see some similarities in Maximus, a power-hungry prince who has an antagonistic relationship with the king.
Unlike the Inhumans comics, which usually focus on Black Bolt and Medusa, the miniseries will feature Maximus as the lead.
Marvel originally planned for Inhumans to be a movie franchise, but last year it shifted over to being a TV series on ABC. By casting an actor like Iwan Rheon and selecting Iron Fist showrunner Scott Buck (Dexter) to run the show, Marvel Studios makes it clear that the eight-episode miniseries will have more in common with Marvel’s Netflix franchise than the more lightweight nature of Agents of S.H.I.E.L.D.—despite the potential for canonical overlap with Agents of S.H.I.E.L.D.‘s Inhuman characters.
Inhumans is scheduled to begin in September 2017, so we can expect to see more casting news in the near future.
