'Game of Thrones' may not have any new footage to show us at Comic-Con 2014 (they haven't even started filming season 5 yet!), but they didn't show up empty-handed. The HBO series revealed the addition of a few new cast members for the upcoming season, which will see some of the action take place in Dorne, home of the late Prince Oberyn Martell.

At today's panel in Hall H, the 'Game of Thrones' crew revealed that they've added more cast members to the line-up for season 5. Previously rumored and confirmed today is the addition of Keisha Castle-Hughes as Obara Sand, a warrior and the oldest daughter of Prince Oberyn Martell. Also added to the cast is 'Da Vinci's Demons' star Alexander Siddig as Doran Martell, the ruling lord of Dorne and the older brother of Oberyn. The people of Dorne will be placing a lot of pressure on Doran in season 5 following the death of their beloved Prince. Toby Sebastian will play Trystane Martell, the young heir to Dorne who is betrothed to Myrcella Baratheon, who will be replaced this season by Nell Tiger Free.

Jonathan Pryce, star of the 'G.I. Joe' and 'Pirates of the Caribbean' films will play High Sparrow, a kind-hearted do-gooder who comes to Kings Landing to help the poor and those who cannot help themselves -- naturally, he'll be getting on Cersei's bad side as he amasses quite the following.

'Game of Thrones' season 5 has also cast DeObia Oparei as Areo Hotah, the captain of Doran's guard; Enzo Cilenti as Yezzan, a slave trader; and Rosabell Laurenti Sellers as Tyene Sand and Jessica Henwick as Nymeria Sand, two more of Oberyn's fierce daughters.

You can watch the official casting reveal in the video above from Comic-Con 2014, and stay tuned as we keep you updated on all the latest 'Game of Thrones' season 5 news.
