The fourth season of the epic fantasy television series Game of Thrones is scheduled to premiere on April 6, 2014, on HBO. It will be based roughly on the second half of A Storm of Swords, the third of the A Song of Ice and Fire novels by George R. R. Martin, of which the series is an adaptation.
On April 2, 2013, HBO announced it had renewed the series for a fourth season, to consist of 10 episodes. Filming for the season began on July 8, 2013, in Northern Ireland. The series will also return to Iceland and Dubrovnik for filming. New locations in Croatia include Diocletian’s Palace in Split, Klis Fortress north of Split, Perun quarry east of Split, Mosor mountain and Baška Voda further down to the south. Filming for the season lasted 136 days and completed filming on November 21, 2013.
“We got more action, which is obviously more time consuming,” says showrunner David Benioff. “It’s a brutal shooting season ahead. But if we can make it through, yeah, I think it’s going to surpass season three. The last 3 episodes, there’s so many scenes we’ve been waiting for so long to do. And it just gets more and more fun to write for these characters. After three years of doing it, we have that much more comfort to make everything uncomfortable for them. We’re very excited for it.”
The Icelandic post-rock band Sigur Rós will appear in season 4. This continues the series’s tradition of employing noted indie bands begun in season 2 with The National and continued in season 3 with The Hold Steady.
