Alcock is part of the up-and-coming cast of the anticipated HBO series “House of the Dragon,” which is a prequel to the popular television show “Game of Thrones,” both of which are based on the “A Song of Ice and Fire” books by George R. R. Martin. The series will chronicle the story of House Targaryen, taking place 200 years before the events of “Game of Thrones.”
She will play a younger Princess Rhaenyra Targaryen, the first child of King Viserys Targaryen and a dragonrider who expects to rule the Seven Kingdoms as the first female monarch. The adult Rhaenyra is portrayed by Emma D’Arcy.
