Welcome to Westeros! The upcoming Game of Thrones prequel, House of the Dragon announced via Twitter today that two new actresses are joining their cast.



Milly Alcock (Reckoning) will portray a young Princess Rhaenyra Targaryen, described on the official House of the Dragon website as “the king’s first-born child, of pure Valyrian blood, [and] a dragonrider. Many would say that Rhaenyra was born with everything…but she was not born a man.”



The second addition to the cast is Emily Carey (Casualty), who will portray a young Alicent Hightower. This character is Otto Hightower’s daughter and “the most comely woman in the Seven Kingdoms.” Otto Hightower is the Hand of the King. Alicent’s “courtly grace” and “keen political acumen” are likely the results of her being raised in the Red Keep, near the king and his “innermost circle.”


The Hollywood Reporter wrote that Alcock and Carey’s roles are listed as “recurring,” meaning that House of the Dragon might show flashbacks to earlier time periods than originally expected. This feature would differentiate House of the Dragon from Game of Thrones as the original series only depicted flashbacks a few times during its eight seasons.

The adult Princess Rhaenyra Targaryen will be portrayed by Emma D’Arcy, while Olivia Cooke is cast as adult Alicent Hightower. Other notable cast members include Matt Smith as Daemon Targaryen, Paddy Considine as King Viserys Targaryen, Steve Toussaint as Lord Corlys Velaryon (“the Sea Snake”), and Rhys Ifans as Otto Hightower.

House of the Dragon is planned to debut on HBO Max in 2022. For more information about the show and its characters, click here!
