This marks the first time producers have talked openly about bringing the epic drama to a close.
“I would say it’s the goal we’ve had from the beginning,” Benioff says. “It was our unstated goal, because to start on a show and say your goal is seven seasons is the height of lunacy.
"Once we got to the point where we felt like we’re going to be able to tell this tale to its conclusion, that became [an even clearer] goal. Seven gods, seven kingdoms, seven seasons. It feels right to us.”
There’s also the tricky, unusual issue of GoT catching up to George R.R. Martin’s source material because the author has released only five of his planned seven-novel Song of Ice and Fire series.
But that's a road the series will head down when/if the appropriate time comes.
Tyrion: Let me give you some advice bastard. Never forget what you are. The rest of the world will not. Wear it like armor, and it can never be used to hurt you. Jon: What the hell do you know about being a bastard? Tyrion: All dwarfs are bastards in their father's eyes.
