HBO's epic fantasy series "Game of Thrones" is currently airing its season four, and with three more episode left fans of the show are looking forward for GOT's season 5. Entertainment Weekly reported recently that the network is scouting for location in the Andalucia region in Spain and "is deep in talks with a local film commission."

If everything will go smoothly during the negotiations, Spain will be the show's seventh country and the main GOT production base will still be at the Titanic Studios in Belfast. The massive production of the show has been shot in many different locations including Croatia for scenes in Kings Landing, Morocco and Malta for Slaver's Bay cities, Iceland for scenes in the north of The Wall and America for bear pit scene.

There is no word yet on which part of the Seven Kingdom is Spain but based on some theories the Spanish landscape could serve as the perfect location for Dorne. Oberyn Martel and Elaria Sand's sunny home, Dorne is located in the southern-most part of Westeros and the hottest region of the Seven Kingdoms.

The following "Game of Thrones" characters who are in talks for casting includes Prince Doran Martell and Prince Trystane Martell according to fan news Web site, "Winter is Coming."

Here are some of HBO's casting predictions.

Prince Doran Martell - Doran is described as the major new player this year, appearing in multiple episodes. The fiftysomething prince uses a wheelchair, is reclusive and rules wisely. It appears the show is looking to continue the trend it started with Pedro Pascal, and cast Latino actors for the Martell clan.

Prince Trystane Martell - Trystane, the handsome fiance of Princess Myrcella, is being aged up to 18.

Areo Hotah - Doran's personal bodyguard will appear throughout the season, assisting the prince with his duties. The show is particularly looking for a African-American actor to fill the role.

The Sand Snakes, Oberyn Martell's bastard daughters (with ages ranging 18-25):

Obara Sand - The eldest and most athletic Sand Snake will be having a major fight scene with a series regular character- not one who crosses her path in the books. This is an interesting change.

Nymeria Sand - Nymeria is described as "mixed race," with her father being the fairer Oberyn and her mother being darker skinned. The second oldest of these Sand Snakes, she's beautiful, emotional and very strong.

Tyene Sand - The youngest of the Sand Snakes that we meet uses her wits and seductive powers, and is less of a physical fighter than the other Sand Snakes. She is just as deadly as her sisters, however, but her weapon is poison.

High Sparrow - The books' pious head of a religious movement will be appearing in several episodes in season 5.

Septa Unella - The show is looking for a character actress to play the imposing and unrelenting septa who spends a lot of time with a major series character next year.

Maggy the Frog - A fortune teller in A Feast for Crows, she'll be in one episode next year.

Lollys Stokeworth - Just last week in "Mockingbird," Bronn announced his intention to marry Lollys, whom Tyrion considers "dimwitted." It looks like the sellsword will still be around next year.

Yezzan - A sleazy Meereenese slave owner.

The Waif - The strange child from the books that Arya encounters will likely be played by an older actress, one in her later teens, and we understand the show is specifically looking for a woman of East Asian descent for the part.
