‘House of the Dragon’: ‘Game of Thrones’ Prequel Adds Milly Alcock and Emily Carey

While The House of Dragon filming began in April, they are still announcing important casting updates. Milly Alcock and Emily Carey are set to star in recurring roles for the new Game of Thrones prequel. The series, created by George R. R. Martin, Ryan Condal, and Miguel Sapochnik, is based on Martin’s Fire and Blood series set 300 years before the first HBO epic, Game of Thrones. It tells the story of the House of Targaryen.

Milly Alcock will play the younger version of Princess Rhaenyra Targaryen. Emma D’Arcy plays the adult version of the princess who is slated to be a major character. As the firstborn child of the king, she is a dragon rider with pure blood. She is the only surviving child of King by his first wife.

Emily Carey will play young Alicent Hightower, daughter of the Hand of the King Otto Hightower. Alicent is considered the most beautiful in the Seven Kingdoms. She was raised at Court in the Red Keep, and her character rises to become a prominent figure. Olivia Cooke (Sound of Metal, Ready Player One) plays the adult version of the character.

Milly Alcock has been on television in Reckoning, Upright, and The Gloaming while Emily Carey might look familiar as she played the younger Diana in Wonder Woman 1984, and as Anastasia in Anastasia Once Upon A Time.

Previous actors cast for the House of the Dragon series include Matt Smith (The Crown, Doctor Who) as Prince Daemon Targaryen, younger brother to the King Viserys, and heir to the throne, Rhys Ifans (Berlin Station) as Otto Hightower, the Hand of the King, and Paddy Considine (Peaky Blinders) as King Viserys Targaryen.

The prequel is co-created by Martin and Condal. Condal, who wrote the pilot script, will also serve as showrunner with Miguel Sapochnik. Sapochnik will also direct the pilot and subsequent episodes. Co-executive producers and writers include Sara Lee Hess, Vince Gerardis, and Ron Schmidt. Greg Yaitanes (who also co-executive produces), Clare Kilner, and Geeta V. Patel will also direct the ten episode debut season.

House of the Dragon is set to debut in 2022 on HBO.
