GateWorld reported that Momoa told fans at the Armageddon Expo in Australia that he got the role, and the Chicago Tribune later confirmed it.
The HBO series is based on the “A Song of Ice and Fire” novels by George R. R. Martin. The book is a planned seven-part series, with four of the books published so far.
In the pilot, Momoa will play Khal Drogo, a wealthy and powerful warrior and horse lord.
The show will also star lena Headey, (“Sarah Connor Chronicles”) Sean Bean, and “New Moon” actress Jamie Campbell Bower (Caius in “New Moon”).
GateWorld also says that Momoa will have a nude sex scene in the show, which female fans will be sure to appreciate.
The series is expected to premiere sometime in the next two years.
