What superhero or villain would you want to play?
"I was always a huge Batman fan. The psychology of that man is so interesting. It's why there have been so many reincarnations."
Who is more ruthless: Arya or Margaery?
"The answer is that Game of Thrones shows all the ways you can wield power. Whether's it's psychological, physical . . . dragons. That's the secret of the writing. That's why the show is compelling. It's about giving people weapons physically and metaphorically and seeing how they use them."
The scene that made you take the part:
"The audition scene for Margaery was where she asks Renly to use Loras, her own brother, instead of her. I had watched season one, and I thought Thrones just wrote three-dimensional complex women really well. I just wanted to be a part of the show."
On Margaery's motivation — evil or well intended?
"Why television is fantastic and is way ahead of film is that it doesn't feel the need to polarize women so much. I experienced it in playing Anna Boleyn as well. . . . Make her the witch, or put her on a pedestal. With Margaery, they said, 'Those aren't mutually exclusive. You don't have to be practical, politically savvy, and a good person. You can be a good human being, but you can also be shrewd. They're not two separate things.' Half the people in this room are female; we're as complex and contradictory as the men, and Margaery reflects that."
On training for the Hunger Games.
"I've had a lot of fun in Hunger Games running around with a semiautomatic rifle. I was ready to get rid of the silk skirts and corsets. But now after nine months of mud and dirt and, yeah, being really physical, I'm ready to go back to the silk skirt."
Would you trade roles with any castmates?
"There's this quiz online: which Game of Thrones character are you? I did it — and I got Arya Stark."
What pisses you off about Hollywood right now?
"It's not fair on you guys, who are watching us. You don't realize how much makeup, how much lighting is going on to make us look good. It's not healthy for young girls to be flicking at magazines and watching these shows. There's a more European feel to French films, in that they're open to the quirks of human nature, that we're not symmetrical, that people are oddballs, aesthetically and emotionally. . . . The best female roles are in television. Except for Katniss Everdeen, who is an anomaly."
What's a unique way to learn a stunt?
"Jennifer Lawrence, when she shoots the arrow, nine out of 10 teams it's CGI put in. That wasn't the case in the first film, but that had to change it for filming reasons. But she shoots arrows, the real thing, for training, constantly. Constantly! So that the action is 100 percent authentic."
What's your favorite kick-ass moment?
"When Margaery says, 'I want to be THE queen.'"
