  ===Cersei's walk of atonement===
  Actress Lena Headey portrays Cersei Lannister in the series.
  For Cersei Lannister's nude "walk of atonement" through King's Landing, HBO employed actress Rebecca Van Cleave as a body double for Lena Headey. While filming the scene in Dubrovnik, Croatia in October 2014, Van Cleave performed fully nude while Headey wore a simple beige shift. Both performances were then merged by the show's editing team, combining close-ups of Headey's facial expressions and long shots of Van Cleave's nude walk through the city. In some instances CGI was used to put Headey's face on Van Cleave's body.
  Headey says that the showrunners decided to cast a body double for "several reasons." Headey says she was glad to use a body double for the scene because she wanted to focus on the character's emotions. Another actor noted that Headey's "extensive tattoos" may have been another reason. Months later, Headey announced that she was pregnant with her second child, though it is unclear if she was pregnant when this scene had to be filmed. Sarah Buchanan of ''Express'' notes the strangeness of casting a much younger actress to play the middle-aged Cersei when the key outcome of the walk of atonement in ''A Dance with Dragons'' is that when the people see that Cersei's body is not beautiful, she loses a large part of her mystique. The 27-year-old Van Cleave did not show any of the specific signs of aging or past pregnancy for which the Cersei of the books was mocked by the crowd.
  When casting for the role, HBO received applications from more than  actresses to act as Headey's body double for the scene. A selection of seven finalists, including Van Cleave, was then flown to Belfast, Northern Ireland to audition before the show's producers. Headey also opted out of the casting process, but director David Nutter said finding the right double was one of the most important parts of making the finale. "We needed somebody who could do The Walk of Shame physically, somebody who could match Lena's integrity, intensity, and sensibility. We found a tremendous actress in Rebecca; she was a godsend. The courage of this girl, who's never done anything like this in her life, who understood what was important about this...once I had her I felt like I could accomplish anything."
  Van Cleave herself described the scene as "one of the scariest, most wonderful, most gratifying experiences I could have imagined ... I never in a million years would have thought I would be in Dubrovnik surrounded by hundreds of extras and crew members throwing food at me, but it was amazing" and "I hope the next thing I do will have my head in it." She also praised Headey's willingness to help her, describing the two of them as a "tag-team"; Headey would walk behind Van Cleave during the shoot, coaching her on the character's responses.
  When the showrunners first announced the plans of shooting a nude scene in Dubrovnik, the city's Catholic Church of St. Nicholas strongly opposed the idea, due to it being immoral to walk their sacred grounds in the nude. Eventually, both parties came to the agreement that the shooting could commence, provided no nude scenes would be filmed in a place of worship. During the three-day shoot, Headey walked Van Cleave through each shot, giving insight into all the emotions Cersei was feeling. The six-minute scene was filmed using 500 extras.
