Milly Alcock: 'High-Up' Official Suggested Acting Coach on 'House of the Dragon' Set

Milly Alcock, the Australian actress who captivated audiences as the young Rhaenyra Targaryen in the acclaimed Game of Thrones spinoff, House of the Dragon, faced a challenging start to her journey. During her appearance on The Tonight Show, Alcock disclosed a humbling experience from her second day on set. A high-ranking individual suggested she needed an acting coach, leaving her "mortified" and questioning her skills. In a light-hearted moment, she quipped, "It just confirmed everything that I’ve kind of known to be true, [which] is that I’m not very good at my job," although she was clearly jesting about her talent.

Despite this early setback, Alcock's portrayal of the iconic Targaryen princess has been well-received. She played a series regular in Season 1 and made a guest appearance in Season 2, which chronicles the decline of the Targaryen dynasty. Emma D’Arcy takes over the role of the adult Rhaenyra, who ascends to the throne.

Milly Alcock's performance in House of the Dragon has earned her a Critics Choice award nomination. The series premiered in August 2022, shortly after the conclusion of the original Game of Thrones. Its success led to a swift renewal for a second season, just days after its debut, and a third season was greenlit in June 2024, even before Season 2 began airing. The show's acclaim culminated in a Golden Globe win for Best Television Series — Drama.

Looking ahead, Alcock is set to expand her repertoire with roles as Kara Zor-El / Supergirl in the upcoming Superman movie and the standalone film Supergirl: Woman of Tomorrow. As for House of the Dragon, while Season 3 is confirmed, fans eagerly await an official release date.
