Four major House of the Dragon actors are going to be replaced in just a few episodes

The most obvious spoiler warning you could ever wish for

For the past two weeks, Game of Thrones fans have been enjoying the opportunity to return to Westeros and indulge in all the usual antics that they get up to over on that damn continent, thanks to House of the Dragon. There's been violence, sex, dragons, knights, deceit, betrayal, feuding. It's good to be back. But if there's one thing fans will have learnt over the years, it's not to get too attached to any of the actors in Westeros, and House of the Dragon will be no different - although maybe not quite for the reason you'd expect. If you've been paying attention to the trailers and the cast list for the series, you may have noticed that there are some actors who we haven't seen at all so far in the show. This is because they are to play older versions of some of the characters later in the series. At the halfway point of the 10-episode series, the story will jump several years forward in time. So it's bad news if you've become a fan of Milly Alcock's portrayal of the feisty Princess Rhaenyra Targaryen or Emily Carey in the role of Alicent Hightower. They will be replaced by Emma D'Arcy and Olivia Cooke respectively. The other two actors who we'll be saying goodbye to after five episodes are Nova Fouellis-Mose, who plays Laena Velaryon, and Theo Tate, who stars as Laenor Velaryon. They will be replaced by Nanna Blondell and John MacMillan respectively as the adult versions of their characters.
