HBO made its annual visit to the San Diego Comic Con today where they announced the nine new cast members set to join the show in the upcoming fifth season. The Dornish play a bit part in next season with seven of the new nine characters tied to the Martell family in some way. The highest profile casting is that of film actor Jonathan Pryce who'll play High Sparrow, the High Septon of the Faith of the Seven (essentially this world's equivalent of the Pope).
