Lena Headey, Hannah Waddingham Revisit Traumatic 'Game Of Thrones' Scene

Lena Headey and Hannah Waddingham recently looked back on their time on "Game of Thrones," including one traumatic scene they filmed.

The two friends reunited for a video chat for Entertainment Weekly, where Waddingham recalled meeting Headey on her first day on the set of the HBO series. They had shot the sequence in which her character, "Shame Nun" Septa Unella, parades a naked Cersei (Headey) through the crowded streets of King's Landing while chanting "Shame!"

"My first day ever on 'Thrones' was standing at the top of those stairs," Waddingham said. "My daughter had popped out maybe nine weeks previously, so I didn't even know what my name was that day. And I said to you, 'Oh, my God, this is so epic.' ... 'Oh, my God, do you ever get used to this?' And you were so cool about it all. And I thought, I want to be like her when I grow up."

Headey chimed in saying that she was "probably terrified about being semi-naked for two days in front of 6,000 people."

They then discussed their disturbing "wineboarding" scene, in which Cersei tortures Septa in the 10th episode of "Game of Thrones" Season 6. Waddingham noted that they both found filming the scene "quite traumatic" at the time.

"People are always quite shocked that that actually did happen in reality and there was nothing CGI'd," she continued. "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. It made wicked telly and I just wondered what your take on all that was, because I think you found it quite difficult too."

Headey confirmed that it was a "horrendous" experience for Waddingham. When someone asked her about the scene recently, she explained that "as an actor, we all have boundaries or no boundaries. And no boundaries are obviously very thrilling when you can go to a place."

However, Headey admitted that she also felt "horrendous" when she did the scene with Waddingham, who was tied down during filming for 10 hours.

The "Ted Lasso" star shared that there was a silver lining in filming those scenes because it helped them feel more comfortable with each other and forge a friendship.

"I have to say one thing 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. "And I was really nervous joining you [on 'Game of Thrones'] because you were like queen lady of the ladies and I was some nobhead who had popped a baby out nine weeks previously."

Headey replied while laughing, "Well, and then you met me and you realized [that I was an] equal nobhead!"

Just recently, Jason Momoa was also asked about a disturbing "Game of Thrones" scene, in which his character Khal Drogo sexually assaults Emilia Clarke's Daenerys in the show's April 2011 pilot episode. The "Aquaman" star told New York Times reporter David Marchese that his question "left a bad feeling in my stomach" and made him feel "bummed."

Momoa and Clarke have maintained their friendship after their stint on "Game of Thrones." In fact, they just reunited at "GoT" co-creator David Benioff's early birthday party celebration and shared several photos of their reunion on Instagram.
