Wētā FX - Take a closer look at the FX simulation created by Wētā FX in House of the Dragon S2 E7. Massive dragon fire simulations were created to blend with live-action fire stunt plates in Dragonmont Gantry for Vermithor’s fiery reaction. Additionally, the live-action beach sequence required realistic sand interaction to effectively convey the dragon’s weight and presence, all with the goal of integrating these majestic beasts into the world of Westeros.
