‘House of the Dragon’ Star Milly Alcock Says Someone ‘Very High Up’ Told Her She Needed an Acting Coach During Her ‘Second Day’ on Set: ‘This Is Terrible’

Milly Alcock had a rough couple of days when first stepping on the set of “House of the Dragon.”

During a recent appearance on “The Tonight Show,” Alcock, who plays young Rhaenyra Targaryen on the “Game of Thrones” spinoff, said that someone “very high up” told her she would be seeing an acting coach during her second day of filming.

“On my second day on ‘House of the Dragon,’ one of the, I’m not gonna say who, but someone very high up, pulled me aside and was like, ‘Um, we’re gonna get you an acting coach,’” Alcock recalled.

She went on to say that the incident did not help her anxiety as she stepped into play Rhaenyra, one of the most iconic characters in the “Thrones” universe.

“It just confirmed everything that I’ve kind of known to be true, is that I’m not very good at my job,” she said. “You know what I mean! I was like, ‘I can’t do this. This is terrible. This is a big mistake.’”

Alcock costarred alongside Emma D’Arcy, Matt Smith and Rhys Ifans in Season 1 of “House of the Dragon,” but only made a brief appearance in Season 2.

Variety recently reported that “House of the Dragon” Season 3 began filming in March. New cast members for the third season include Tommy Flanagan, Dan Fogler, Tom Cullen, Joplin Sibtain and Barry Sloane.

“House of the Dragon” is set about 200 years before the events of “Game of Thrones,” and is based on the fantasy novel “Fire & Blood” by “Thrones” mastermind George R.R. Martin.
