Lena Headey and Hannah Waddingham of Game of Thrones have teamed up to talk about the ‘horrific’ 10-hour day they spent shooting a torture scene.

Both actresses have spoken about how difficult it was to film the scene in which Cersei Lannister tortures Waddingham’s Septa Unella over the last several months.

“I wanted to ask you, which we never really talk about because I think both of us found it quite traumatic at the time – our waterboarding, or rather wineboarding, scenes,” Waddingham said in a new partnered interview for Entertainment Weekly.

“It made wicked telly and I just wondered what your take on all that was, because I think you found it quite difficult too,” she said.

“People are always quite shocked that that actually did happen in reality and there was nothing CGI’d. One thing I’ve said a lot is that both of us were quite uncomfortable about it, but as with all these things, you know that they’re not actually going to kill you so you just get on with it and do it.”

“Yes, that was, for you, horrendous,” Headey said.

“Someone else asked me about that the other day and I was like, you know, as an actor we all have boundaries or no boundaries.

“And no boundaries are obviously very thrilling when you can go to a place… but something like that when you’re tied down, it made me feel horrendous doing that scene with you.”

Waddingham said the event drew them closer together, despite the fact that “it made wicked telly.”

“I have to say one thing that, that traumatic experience — and you walking through the streets practically with your nunny out — gave us was that you and I absolutely became incredibly close,” Waddingham said.”
