  === Overview ===
  In the HBO television adaptation, Aimee Richardson portrayed Myrcella for the first two seasons. Initially cast as a stand-in, Richardson impressed the crew enough to be kept as a full cast member; she appeared in eight episodes. Nell Tiger Free played Myrcella for the seasons five and six. Prior to her audition, Free had never seen the show; when talking about the role, she said: "I mean, it’s every kids dream to play a princess and the dresses were fantastic." Richardson learned about the recasting at the San Diego Comic-Con; in response, she posted a Vine video in which she wore a crown and held a sign saying "Princess for Hire". An explanation was not given for the change in actors.
  Mycella's fate was one of several differences between how the television show and the novels represented the Sand Snakes and Dorne. Her death scene was originally longer with parallels to Joffrey's death; it would have involved her head exploding and gore splattered throughout the set. Discussing these changes, Free said: "David Benioff and D. B. Weiss wanted Myrcella’s death to reflect her life, and wanted it to be sweet – which is rare for Game of Thrones." ''Esquire'''s Matt Miller wrote that the final version was tamer in comparison to other characters' deaths. Free appeared in six episodes of the show.
