On Sunday night’s Game of Thrones episode “Battle of the Bastards,” director Miguel Sapochnik pulled off something that many directors try and very few achieve: a battle sequence that moves smoothly from large-scale troop movements to intimate confrontations between soldiers. He did it in such a way that everything was legible to viewers while finding time to show how little sense the chaos of war made to a soldier on the ground.

Chaos of war scenes are a dime a dozen—though the minutelong shot of Jon Snow in the center of the battle is an extraordinary example—but legible large-scale tactics are much rarer. Good luck reverse-engineering Agincourt from Olivier’s Henry V (a clear influence here), to say nothing of lesser efforts.
