Ryan Condal on House of the Dragon Season 3: "It's the Biggest Thing We've Ever Done"

Ryan Condal is willing to put his legacy on the line. The House of the Dragon showrunner arrived at the ATX TV Festival in Austin this weekend with a bold claim and the production numbers to back it up: that the Season 3 premiere is, from a pure filmmaking standpoint, one of the most technically demanding episodes of television ever made.

Producing the third season took 314 shooting days and more than 25 tons of propane. The first episode dives straight into the Battle of the Gullet, the catastrophic naval engagement that has loomed over the series since Season 1 — and Condal did not undersell what it required to put on screen.

“So much of this episode is practical,” he told the audience inside the Paramount Theatre. “You’re in the water; there are multiple ships interacting that are real physical sets, and the fire and the dragons and all these things knitted together just seem like it’s all happening in the same place at the same time.”

The water work alone demanded an engineering solution the show had never attempted. The production used two tanks: a dry tank with gimbals that rock and pitch to simulate open-sea motion, and a wet tank for sequences requiring interactive water — actors falling overboard, ramming, boarding planks, close-quarters medieval combat. “In medieval combat,” Condal explained, “most of the naval battles we’re used to seeing, there’s gunpowder involved. In this world, there is none, so you got to get really close to each other.”

Condal acknowledged the weight of calling it “arguably the craziest episode of television ever made,” laughing that it “might now be written on my tombstone” — but stood by the claim on purely process grounds. “It really is this amazing achievement of filmmaking on an artistic level, from all the crafts and crew that go into it,” he said. “We live in this era where really you can kind of do anything on film, and I think a lot of our brains just go, ‘Oh, that’s all just CG.’ A lot of people are making big TV now, but it’s the biggest thing we’ve ever done, for sure.”

The season also reframes the Targaryen civil war through the lens of nuclear deterrence. “There are nuclear weapons in play on both sides,” Condal said. “Really you have this classic Cold War standoff of mutually assured destruction… But, of course, that builds and builds and builds, and at some point the cork comes off the champagne bottle, and that’s where we begin here in Season 3.” He also promised both new dragons and extensive screen time for returning favorites — though warned that fans who have grown attached to them may not enjoy where the story is headed.
