Why House of the Dragon Recast Rhaenyra Targaryen and Alicent Hightower

However, by Season 1, Episode 6 of House of the Dragon, “The Princess and the Queen,” the actresses playing Alicent and Rhaenyra were replaced. Olivia Cooke took over the role of Alicent, previously played by Emily Carey, and Emma D’Arcy replaced Milly Alcock as Rhaenyra. While the relationship between the two characters stayed consistent, Alcock and Carey didn’t continue in their roles. Though understandable due to the ten-year time jump in the story, the decision to recast them still feels strange.
