"It's also the one I'm proudest of because it was the hardest."
Benioff added the forthcoming episodes, due to return to screens on April 24, turned out better than expected.
"This is not us trying to hype it," he told EW.
"Usually, there's an episode or two we're kind of nervous about, that didn't turn out as well as we hoped."
"This season there is not a weak episode. We had great directors who knew what they were doing paired with excellent [directors of photography]."
"We thought at the script stage it might be our strongest season. Then the episodes came in better than we hoped."
