For many actors, filming an intense dramatic scene can be emotionally demanding. But for Hannah Waddingham, one particular moment on the set of Game of Thrones pushed the limits of what she expected to endure as a performer. The scene involved her character, Septa Unella, facing punishment from Cersei Lannister—a moment that became infamous both on screen and behind the scenes.
In the series, Septa Unella is introduced as a stern religious figure aligned with the militant faction known as the Faith of the Seven. She is most remembered for relentlessly ringing a bell and chanting “shame” during Cersei’s humiliating walk through King’s Landing. However, the story eventually takes a dramatic turn when Cersei regains power. Determined to exact revenge, the queen imprisons Unella and subjects her to psychological torment in a dark cellar beneath the Red Keep.
While the sequence appears relatively brief on screen, filming it was far more grueling than viewers realized. According to Waddingham, the production process required her to remain strapped to a table for extended periods while liquids were poured over her face to simulate torture. The sequence had to be filmed repeatedly from multiple angles, meaning the same action was recreated again and again throughout the day.
The actress later described the experience as one of the most physically difficult moments of her career. For nearly ten hours, the production team repeated the scene to capture the emotional intensity required for the storyline. Though special effects and safety measures were used to simulate the ordeal, the repeated takes still created a deeply uncomfortable environment for the performer.
Waddingham has spoken openly about how the situation affected her. She experienced intense claustrophobic feelings during filming, and the constant strain on her voice while shouting and reacting in character placed pressure on her vocal cords. The emotional realism visible in the final scene, she explained, was partly the result of genuine exhaustion and stress after hours of demanding work.
Members of the cast and crew reportedly recognized how challenging the sequence had become. Watching a colleague endure such a physically taxing performance left a strong impression on many people present on set. It also demonstrated how committed actors sometimes must be to delivering powerful moments in major television productions.
Despite the difficulty, Waddingham ultimately delivered a performance that contributed to one of the show’s most memorable storylines. Game of Thrones became famous for its dramatic confrontations, shocking twists, and morally complex characters. Scenes like the confrontation between Septa Unella and Cersei helped reinforce the brutal political atmosphere that defined the world of Westeros.
In the years since the episode aired, Waddingham has gone on to achieve global acclaim in other projects, including her celebrated role in Ted Lasso. Her portrayal of Rebecca Welton earned critical praise and major awards, introducing her talent to a new generation of viewers.
Looking back, the actress has acknowledged that the difficult day on the Game of Thrones set remains unforgettable. While the scene lasted only a short time in the finished episode, the experience behind it highlighted the intense dedication often required in large-scale television productions.
For Waddingham, it stands as a reminder of both the physical demands of acting and the resilience needed to bring challenging characters to life. Even the most difficult days on set can become part of a performance that audiences remember for years.
