Some Game of Thrones Season 5 scenes are already being filmed in Sevilla, Spain, based on this report on zap2it.com. This new location is believed to be the setting for Dorne.

In other news, Aiden Gillen told news.com.au Littlefinger's relationship with Sansa Stark is not a simple matter of sexual desire. Still, their relationship changes drastically in Game of Thrones Season 5.

In the Capital, the death of Prince Oberyn Martell (Pedro Pascal) in the (bare) hands of The Mountain aka Gregor Clegane (Hafþór Júlíus Björnsson) has consequences for the Queen Regent, Cersei Lannister (Lena Headey). In Game of Thrones Season 5, Cersei becomes the most powerful Lannister, following the death of Joffrey (Jack Gleeson) and Tywin (Charles Dance).

"There will be Dorne, and we're excited about it," GoT showrunners David Benioff and D.B. Weiss told the Entertainment Weekly in an interview about Game of Thrones Season 5.

"Now that we're nearly finished with the first drafts of each episode [for GoT 5], we see no reason why the coming season shouldn't be the strongest yet," the show bosses said, hinting at an even richer set of storylines for the Lannisters, Starks, and Daenerys Targaryen (Emilia Clarke) in Game of Thrones Season 5.

Making headlines the past couple of days is George R.R. Martin, who has reacted, quite bluntly, to those worried he might not live long enough to finish his book series, "A Song of Ice and Fire." HBO President of Programming Michael Lombardo and Chairman and CEO Richard Plepler were recently asked if they have "any concerns" on the same issue.

"Certainly after next year [for Game of Thrones Season 6], we will have to figure it out with George, if his book's not finished. We're in conversations with him, but we're not concerned about it," Mr Lombardo told collider.com.

"[Sansa is] playing [Littlefinger] now. I think that's what's gonna happen there. I don't know what she's doing, but she could be playing him. It can only get more interesting," Gillen also told news.com.au.

Gillen says Littlefinger's efforts toward helping Sansa is not all about "trying to seduce her." When it comes to the blossoming Stark, Gillen noted the "spontaneity and things happening that he's not in control of." More of this is expected in Game of Thrones Season 5.

Sansa Stark (Sophie Turner) was last seen in Game of Thrones Season 4, wearing a dark feathery long gown, ready for the day's next battle, asking, "Shall we go?"

The Game of Thrones Season 5 premiere is still about nine months away, but GoT fans are too excited to skip spoilers online.
