House of the Dragon season 3: actors discuss the brutal battle and shocking kiss

Showrunner Ryan Condal explained that the Battle of the Gulf sequence, originally not planned for the opening of season 3, was moved to give the episode the needed weight and to balance the season’s pacing. The two‑year preparation involved months of actor training and extensive practical effects, with much of the combat filmed “live” on set.

Actors Olivia Cooke and Ewan Mitchell described the episode’s controversial kiss between Alicent Hightower and her son Aemond, characterising it as a disturbing expression of twisted affection. Cooke said the scene felt “dangerous” and “very unsettling,” while Mitchell portrayed Aemond’s desperate need for maternal love. The discussion also highlighted other intense moments, such as the naval clash involving Corlys Velaryon’s fleet and three dragons, and the grueling physical demands placed on cast members during the battle shoot.
