House Of The Dragon Continues To Beef Up Its Cast

HBO's "Game of Thrones," based on the "A Song of Ice and Fire" book series by George R. R. Martin, was just about the most popular show on the planet while it aired from 2011 to 2019. In fact, the series finale, "The Iron Throne," became the most-watched episode ever for HBO, with its whopping 19.3 million viewers, as reported by Deadline. Naturally, HBO has taken the opportunity to continue with the "Game of Thrones" story — a prequel series, "House of the Dragon" was announced in October of 2019 (via The Hollywood Reporter).

"House of the Dragon" is based on Martin's 2018 novel, "Fire & Blood," and will focus on House Targaryen and take place 300 years before the events of "Game of Thrones."

Not long after the series order was announced, we found out that British actor Paddy Considine would be taking on one of the lead roles, King Viserys I Targaryen (via Entertainment Weekly). Since then, the series has added actors such as Matt Smith ("The Crown"), Olivia Cooke ("Sound of Metal") and Emma D'Arcy ("Hanna") to its roster.

And the cast list only keeps getting bigger, with two more actors having just been announced.

The Hollywood Reporter has reported that "House of the Dragon" has added two more actors to the growing cast. Milly Alcock, who has most recently appeared in the Australian miniseries "Reckoning," will play the younger version of Emma D'Arcy's character, Princess Rhaenyra Targaryen. On the show's official site, Rhaenyra is described as "The king's first-born child. She is of pure Valyrian blood, and she is a dragonrider. Many would say that Rhaenyra was born with everything ... but she was not born a man."

Additionally, Emily Carey, who has a recurring role on the British series "Casualty" and appeared in 2017's "Wonder Woman" as a young Diana, has also been cast. Carey will play the younger version of Olivia Cooke's character, Alicent Hightower. Alicent, the daughter of Hand of the King Otto Hightower, is described as "the most comely woman in the Seven Kingdoms." She has both "a courtly grace and a keen political acumen."

Previously announced cast members also include Matt Smith as Prince Daemon Targaryen, Steve Toussaint as Lord Corlys Velaryon aka "The Sea Snake," Eve Best as Princess Rhaenys Velaryon, Rhys Ifans as Otto Hightower, Sonoya Mizuno as Mysaria and Fabien Frankel as Ser Criston Cole.
