Game of Thrones co-showrunner Dan Weiss reveals that season 7 premiere (Dragonstone) originally did not have the cold open we saw but David Bradley’s (Walder Frey) performance made them change their minds:
“The cold open wasn’t initially the cold open. We had organized the episode a bit differently. But when we saw David Bradley’s performance, and seeing the subtle move that he made to not quite be Walder Frey but to start as Walder Frey and end as Arya Stark, that made us realize that this was the best way to open the episode of this season.”
