Ramsey Bolton (Iwan Rheon) cast in Marvel's Inhumans show

Marvel's upcoming Inhumans series cast its first lead, Iwan Rheon. Rheon will be playing Maximus the Mad, a member of the Inhuman and Attilan Royal Family. He is the brother of Blackbolt (the king). Deadline reported the character as described as “a clever and charming Inhuman that is fiercely devoted to the people of Attilan, especially his brother, the King – although he harbors an intense desire to wear the crown himself.”

Rheon is best known for excellently portraying ultra scumbag Ramsey Bolton on Game of Thrones, so this casting couldn't be any more perfect. 

Maximus is extremely intelligent, has enhanced strength as part of his Inhuman biology, and strong mental powers including mind control.
