House of the Dragon was the first production to use Warner Bros. Studios Leavesden's new V Stage, pairing a large wraparound LED volume with realtime previs, in-camera environment work, and hybrid LED / bluescreen methods for demanding dragon, flight, and large ensemble sequences.
Leavesden states the series filmed extensively at the studio using V Stage, four sound stages, and the backlot. The ASC feature adds that the LED volume accelerated iteration once the team climbed the learning curve, with the workflow becoming far faster over time.
