At the panel, producers dished some major casting spoilers, naming a slew of new faces who are joining the show.
Alexander Siddig as Doran Martell. Some fans thought this Star Trek veteran would make a good Oberyn, but instead he joins the cast as Oberyn's scheming older brother, Doran Martell. Works for us!
Three Sand Snakes. The Sand Snakes are Oberyn's bastard daughters. In the books he has eight, and we'll apparently be meeting at least three of them this season: Jessica Henwick as Nymeria Sand, Rosabell Laurenti Sellers as Tyene Sand, and Keisha Castle-Hughes (pictured left) as Obara Sand.
Nell Tiger Free as Myrcella Baratheon. We've already met Cersei's only daughter, who, much to her mother’s displeasure, is currently living in Dorne, but she has been recast since the last time we saw her sailing away.
Toby Sebastian as Trystane Martell. Doran's youngest son, engaged to Myrcella.
Jonathan Pryce as the High Sparrow. Jonathan Pryce will play the High Sparrow, the High Septon of the Faith of the Seven (think a Pope-type religious leader).
DeObia Oparei as Areo Hotah. The captain of Doran Martell's guard.
Enzo Cilenti as Yezzan. A wealthy slave trader in Yunkai.
