House of the Dragon is set across a much wider time frame than GoT. So, some of the younger actors will replaces by older ones for episode six - including 22-year-old Alcock, who plays the King's daughter Rhaenyra. The older Rhaenyra, who will be around a decade older, will be played by Emma D'Arcy. The 30-year-old Londoner has previously been seen in comedy horror series Truth Seekers by Nick Frost and Simon Pegg, and Netflix drama Wanderlust.

Speaking at the LA premier, Cooke said Alicent is the "complete polar opposite of who she is". Related links:
