Milly Alcock Shares How the House of the Dragon Cast Kept Cool on “Incredibly Hot” Set

But the heat wasn’t the only challenge for the actress, who exclusively told E! News that filming the dragon-riding sequences was not her “favorite thing.” The sequence required the actors to sit on a rig in front of a screen that projects the landscape from the show in the background.

Milly wasn’t the only House of the Dragon star who had to adjust to using the dragon rig. Her co-star, Eve Best, who plays Princess Rhaenys Velaryon, told E! News how she felt about the dragon-riding scenes.

“It’s a machine and it’s moving about, and you have to move like you’re on a motor bike which I’ve never done before,” she noted. “You’re strapped in a harness and there’s wind in your face. It’s just quite weird, but it was also quite lovely.”

House of the Dragon has already been renewed for a second season after the show broke records with its Aug. 21 premiere—according to the network, the debut episode saw the largest audience for any new original series in HBO history. The show takes place 200 years before the events of Game of Thrones, when the House Targaryen ruled over Westeros. In addition to Alcock and Best, the show stars Tom Glynn-Carney, Emma D’Arcy, Rhys Ifans, Emilia Carey, Olivia Cooke, Steve Toussaint, Fabien Frankel, Sonoya Mizuno, Paddy Considine and Matt Smith.
