The upcoming season of hit HBO historical fiction drama "Game of Thrones" is highly anticipated by fans, and according to the stars and show creators, this season will be an eventful one.

For spoilers from showrunner David Benioff and star Peter Dinklage, read on.

David Benioff recently sat down for an interview with Entertainment Weekly where he said he is expecting big things for the new season.

"It's the toughest production schedule we've ever had. We got more action, which is obviously more time consuming. 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 three 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," the showrunner said.

"After three years of doing it, we have that much more comfort to make everything uncomfortable for them. We're very excited for it. Season five gives me nightmares, but [not season four]," he added.

Peter Dinklage, who plays Tyrion Lannister in "Game of Thrones" also spoke about the upcoming season.

"T the scripts these guys have turned out are my favorite so far of the whole series," Dinklage said.

It is expected that the forth season of the HBO drama will be heavily based on "A Storm of Swords," and "A Feast for Crows," which are the third and fourth books, respectively, in the series penned by George R. R. Martin.
