Milly Alcock has become one of the breakout stars of the show so far, so the news that she is being replaced might be a hard pill to swallow for some viewers. The Princess of Dragonstone and heir to the Iron Throne will be played by British actor Emma D’arcy going forward. Emma, who identifies as non-binary and uses they/them pronouns, has previously starred in the film Misbehaviour, the Netflix series Wanderlust and Amazon Prime movie Truth Seekers.

Queen Alicent Hightower was portrayed by Emily Carey for the first five episodes, but like her former BFF, is also getting aged up for the remainder of the season.

Viewers will recognise the actress as last year, she appeared in the critically acclaimed Sound of Metal alongside Riz Ahmed and more recently, she has been seen in the Apple TV+ series Slow Horses.

The eldest of the Velaryon children, Laena Velaryon, has actually been played by two actresses already - Nova Foueillis-Mosé as a child and Savannah Steyn as a teen - but now Swedish star Nanna Blondell is taking on the role. Viewers might recognise the actress from her roles in the Marvel movie Black Widow and Netflix’s Red Dot.

Laena isn’t the only Velaryon with a new look as her brother Laenor Velaryon is also being replaced with a new actor. The son of Princess Rhaenys and Lord Corlys - and now King Consort to Rhaenyra - was previously played by Theo Nate but now will be played by John Macmillan. The actor’s TV credits include Famalam, Chewing Gum and Back.

 Aegon Targaryen is all grown up - and ready, it seems, to fight his sister for the Iron Throne. Lord Viserys’ and Alicent Hightower’s eldest child is being played by newcomer Ty Tennant for the rest of the series. If you’re wondering why he looks familiar, it’s because the 20-year-old actor is the eldest son of David and Georgia Tennant.
