HBO’s “House of the Dragon” has cast the younger versions of two very important characters in the “Game of Thrones” prequel series: Princess Rhaenyra Targaryen and Alicent Hightower.
Set 300 years before the events of “Game of Thrones,” “House of the Dragon” tells the story of House Targaryen, the ancestors of Emilia Clarke’s Daenerys Targaryen. The series, which is based on “Game of Thrones” author George R.R. Martin’s “Fire & Blood,” is set to debut in 2022.
Milly Alcock (above left) is set to play the part of Young Princess Rhaenyra Targaryen, the king’s first-born child. She is of pure Valyrian blood, and she is a dragonrider, per the character description.
