(Director: Rolling, rolling.)

(Crew member: Cue marker.)

Director of photography: The fun thing about the Arya and Brienne thing was, I don't think we had to do too much to it to make it really fun to watch, because everybody's wanted to see these two together for a long time. And if they didn't know they did, they certainly do the minute the two of them meet.

(Maisie: Nice.)

Gwendoline: It was so exciting to train for that fight. And we trusted each other.

Maisie: But to be fighting Gwen, who is far over a foot taller than me, and for her to be, you know, fighting someone who's far, far shorter than her, it's been a massive challenge.

Stunt coordinator: Generally, as you attack, you move forward, and as you defend, you move back. And they have completely different sizes of gait, of step. That was a big challenge to choreograph that and deal with those issues.

Stunt coordinator: We used stunt doubles for their skill sets, and also to put them in harm's way to a degree.

Director: Three, two, one, action!

Gwendoline: In a fight, it's so much more than ... just choreography. (Characters fight.) Every movement says something about the character. It tells the story of these two very different warriors.

Gwendoline (playing Brienne): Who taught you how to do that?

Maisie (playing Arya): No one.
