Thrillist: You filmed Fighting With My Family in between seasons seven and eight of Thrones. Is there a temptation to relax during that period? What made you want to go and do this?
Lena Headey: I saw the documentary [on which the movie is based] and fell in love with the Knight family, and I wanted to do some comedy. It was something very different and probably unexpected. And then I got the script from Stephen. Because I knew the documentary, I was really excited they were going to do the film version of this family.
How familiar were you with the wrestling world? You've done a bunch of action, but did you know wrestling moves?
Headey: No wrestling knowledge. I grew up watching old British wrestling, which was fat guys in unitards drinking pints and smoking cigarettes. I knew of the WWE because it's unavoidable. But yeah, I wasn't versed in any wrestling knowledge.
Did you have to train? What was it like wrestling with Nick Frost?
Headey: Wrestling with Nick Frost is hilarious, as most things with Nick Frost are. It was great. I didn't do any physical training. We obviously rehearsed that fight that we do with stunt doubles and us.
Knowing your social media presence, there's often a lot of goofy stuff going on, but you haven't had the opportunity to show that side of yourself on Thrones, for instance. What was the impetus to do more comedy?
Headey: I don't want to say I'm, like, hilarious, but obviously Cersei's sort of permeated everything. More than anyone ever thought would happen. So I think there's a preconception of who I am. That follows you weirdly in this industry, even with industry professionals who are like, "Oh God, you're funny and nice." Where I lay naturally as a person is more relaxed and nerdy than playing wicked queens.
When you say permeated what do you mean?
Headey: Just that Thrones has become so massive unlike anyone ever thought it would, and it's become part of a language now. The characters are used to represent things that have happened in the news.
Did you know Florence at all? Because her brother was on Thrones as Trystane Martell.
Headey: No, I never met Toby [Sebastian] all the time we did Thrones. I obviously hadn't met Florence, but I knew of her. She's kind of rising and brilliant. It's unavoidable. She's everywhere, quite rightly.
Did you talk to her about this weird intersection?
Headey: I think in passing. She was like, "He was on Thrones." I was like, "Yeah, I know." Then we continued slamming each other against the ropes.
