showrunners, David Benioff and Dan Weiss, have signed a deal for two more season with HBO, according to Entertainment Weekly. Benioff and Weiss were the ones who originally brought the idea to adapt George R.R. Martin's A Song of Ice and Fire novels to HBO. They have acted as writers, producers, and directors for the show and have earned multiple Emmy nominations for their work. Though the showrunners signed a two-season deal, the show has not officially been renewed for a fifth season as of yet. Of course, with it being the most successful show to air on HBO since The Sopranos, it would be pretty shocking if it didn't get renewed. In Game of Thrones Seasson 4, encouraged by the Red Wedding slaughter in the Riverlands that wiped out many of their Stark nemeses, the Lannisters' hold on the Iron Throne remains intact… but can they survive their own egos, as well as new and ongoing threats from the south, north and east? While an unbowed Stannis Baratheon continues to rebuild his army in Dragonstone, a more immediate danger comes from the south, as Oberyn Martell, the Lannister-loathing "Red Viper of Dorne," arrives at King's Landing to attend Joffrey's wedding to Margaery Tyrell, and perhaps act on an ulterior agenda. In the north, a depleted Night's Watch seems overmatched against the inexorable Wall advances of Mance Rayder's army of wildlings, which in turn is being trailed by an even more formidable foe: the undead White Walkers. As if that weren't enough, Daenerys Targaryen, accompanied by her menacing trio of dragons and army of Unsullied, is poised to liberate Meereen, the largest city in Slaver's Bay, which could ultimately provide her with enough ships to sail to Westeros and reclaim the Iron Throne. Game of Thrones Season 4 premieres Sunday, April 6 on HBO.
