Season 6

Season 6 of Game of Thrones was formally commissioned by HBO on 8 April 2014, following a substantial increase in audience figures between the third and fourth seasons. The fifth and sixth seasons were commissioned simultaneously, the first time HBO has done so for a major drama series.

The season consists of ten episodes. It began filming in July 2015 and will conclude late into the year. David Benioff and D.B. Weiss return as executive producers and showrunners for both seasons five and six, having signed a new two-year contract with HBO in early 2014.

The season is expected to premiere in Spring 2016.

Season 6 will be based on the hitherto unreleased sixth novel of the A Song of Ice and Fire book series, The Winds of Winter, along with a significant amount of leftover material from the fourth and fifth books, A Feast for Crows and A Dance with Dragons, which run concurrently but follow different sets of characters.

Adaptation
While prior seasons followed a format of adapting roughly one book's worth of material per year (or one large book across two seasons, in the case of Season 3 and most of Season 4), Season 5 condensed together most of the fourth and fifth novels in the A Song of Ice and Fire series, A Feast for Crows and A Dance with Dragons, resulting in most storylines catching up with the end of the fifth and most recent novel, in particular Jon Snow and the Night's Watch; Daenerys Targaryen and Meereen, including Tyrion Lannister; Cersei Lannister (yet not the rest of King's Landing, such as Margaery Tyrell after her imprisonment and Kevan Lannister after Cersei's walk of atonement); Petyr Baelish and the Vale; Sansa Stark, whose storyline was merged with Jeyne Poole's, the one forced to marry Ramsay; Stannis Baratheon and Melisandre; Davos Seaworth, who was involved in another subplot in the North which was cut or delayed; Roose Bolton and Ramsay Bolton; Bran Stark, Hodor, and Meera Reed, who almost caught up at the end of the fourth season; and Theon Greyjoy. However, other characters did not yet catch up: Arya Stark has two more chapters after going blind at the end of the fourth book (though parts of the first chapter from the sixth novel were featured in Season 5, in which she killed Meryn Trant instead of Raff); and, while most of the original story in Sam and Gilly's voyage was already adapted in the fifth season before they even left Castle Black (including their growing relationship, learning of Daenerys ruling in Slaver's Bay, and Aemon's death), their journey in the fourth book also included a brief stay in Braavos, and by the end they arrived in Oldtown and he met the maesters at the Citadel. While House Martell and Dorne's substantive plot was technically included, it was drastically condensed, omitting most of its characters, most prominently Doran's daughter and heir Arianne Martell, who was the lead of the subplot (while in the show a main character —Jaime Lannister— was sent to fill that role), and also most of their machinations (to the point that Doran Martell only appeared briefly), effectively delaying the climax of the storyline to Season 6.

Although most storylines from the fourth and fifth books were included in Season 5 in some form and to some extent, there was simply too much material to fit it all in one season, so several subplots were delayed to Season 6, in particular House Greyjoy and the Iron Islands and House Tully and Riverrun, who haven't been a major presence in the show since Season 2 and Season 3 respectively, yet have major subplots starting in the fourth novel, with Yara Greyjoy as a new POV narrator and with Brynden Tully in charge of Riverrun after the Red Wedding massacre. Nevertheless, somes changes are inevitable, especially in regards to the links between these subplots and the King's Landing storyline, since the context for the interactions between the Crown and these rebel Houses changes depending on who is in charge of the Crown —which shifts drastically before and after Cersei's deposition. It is also unknown whether or not these subplots will progress far enough they reach material taken from The Winds of Winter.

These notable exceptions notwithstanding, the sixth season will mostly draw upon the as-yet-unpublished sixth novel, The Winds of Winter. George R.R. Martin did give the TV producers a general outline of events that will happen in the final two unpublished novels, though the adaptation process will fundamentally change, as the writers won't have access to fully finished source material. Though Martin has released about half a dozen preview chapters from the sixth novel, it isn't clear if they can really be the basis of any future material in the TV series, due to already existing differences between the book series and the TV adaptation. Also, until the book is released, there is no way of analyzing the adaptation process properly (e.g., if the actions of one character in Season 6 are actually a condensation of the actions of two different characters in the sixth novel).

Production
In Northern Ireland, production would run for five months, from late July to early December. Interior shooting returned to the show's headquarters, the Paint Hall Studios in Belfast. Meanwhile, location shooting took place at the following locations: Garron Point (previously Runestone), the Winterfell set in Moneyglass , Magilligan (reprising its part as the Dothraki sea) , the Castle Black set in Maghermorne , Ballintoy (returning as Pyke) , Sallagh Brae in Larne (where a small sept set was built) , Glenarm (previously the Vale) , Carnlough Harbour (as a Braavosi canal) , Shane's Castle (once more as the foundations of the Great Sept of Baelor) , Carncastle (previously the fields around Winterfell) , Aghanloo Wood , Saintfield (as the site for "The Battle of the Six Armies" , a climactic Northern battle , which demanded the show's lengthiest shoot for a battle scene) , the new Riverrun set in Corbet (built for the first time, since in the third season the castle was realized only with Gosford Castle's gardens, an interior hall set and a distant matte painting for a single shot), the quarry on Knocklayd Mountain , Ballycastle in County Antrim, and Marlough Bay.

Ever since Croatia was introduced into the production for the second season, it has been the main source of locations outside of Northern Ireland, yet this season only returned to the country for a brief shoot in Dubrovnik, which reappears as King's Landing. Previously, Dubrovnik had been both King's Landing and Qarth, while Klis, Split and Šibenik depicted Meereen and Braavos. This season turned to new Spanish locations instead.

In Spain, filming took place between late August and late October. In Girona, the locations were the Sant Pere de Galligants abbey's exterior (as a Braavosi bridge) , the Plaça dels Jurats (as a Braavosi theater stage) , the streets of Ferran el Catòlic, Sant Martí and l’Escola Pia (as Braavosi marketplaces) , another local street (as an alley in Oldtown) , and the Girona Cathedral's exterior (as the Great Sept in King's Landing). Still in Catalonia, they filmed in the Santa Florentina Castle (as Horn Hill), Montgrí Castle and Besalú. Later locations where the Bardenas natural park in Navarre (as the Dothraki Sea) and the Zafra Castle in Guadalajara (as the Tower of Joy). In Peñíscola, all filming spots posed as Meereen: the Portal Fosc (as a dilapidated street) , the Plaza de Santa María (as a granary) , the Parque de la Artillería (as a garden) and the Plaza de Armas. In Almería, filming took place at a new Vaes Dothrak set in Pechina , on the Tabernas desert (as the Dothraki Sea) , on the Gypsum Karst of Sorbas , at the Mesa Roldán Tower (as Meereen) and at the Alcazaba (as Sunspear).

Crew
On March 27 2015, author George R.R. Martin said he would again not write a script for Season 6, as he wished to concentrate on finishing The Winds of Winter as soon as possible. On June 4, Miguel Sapochnik indicated he was already preparing to direct next season. Jeremy Podeswa made similar statements in June 12. On June 19, the showrunners confirmed that April Ferry would be the new costume designer for Season 6, replacing Michele Clapton, who decided to leave after five seasons. On June 22, newcomer Jack Bender announced he would direct two episodes for season six. The full list of directors and which episodes they would oversee was released in Entertainment Weekly on June 25. There will be five directors, each doing two back to back episodes, as in Season 5. Jack Bender and Daniel Sackheim are working on the TV series for the first time, while the other three directors previously worked on the series in Season 5; none worked on the first four seasons.
