We're used to Westeros going big, but "House of the Dragon" season 3 will be "massive," per a new production update from series creator Ryan Condal.

When the "Game of Thrones" prequel series returns on HBO and HBO Max sometime in 2026, viewers will be thrown in the middle of a massive civil war between two opposing factions inside House Targaryen: Team Black (the contingent that supports Rhaenyra Targaryen as heir to the crown) versus Team Green (those that back her half-brother Aegon II Targaryen's claim to the Iron Throne).

With on-location filming officially wrapped in Wales (the production will now move to in-studio sets in the U.K.), Condal gave an anticipated update on season 3 during a July 2025 episode of his podcast "The Stuff Dreams Are Made Of" with co-host David Mandel.

"We're right in the middle of production. We've wrapped Wales, we're moving on to some huge things now that we've got going at the studio and then other locations that we're working on, so we've moved into that part of the schedule," Condal shared.

"It gets pretty nuts here through July and August. So I will be rushing off to set tomorrow to do the beginning of some insane things that we're doing this month."

He continued, "But yeah, we're right in the middle in the thick of it, and it's going great. I mean, the season is just goddamn huge.

"Every day I walk around there and look at the things that we're building and the things that we're doing and the number of costumes and extras and all that ... I knew it was bigger than season 2, but I don't think I realized quite how much."

The new episodes boasting a grander scale shouldn't come as a surprise to "House of the Dragon" fans, what with the impending succession war between Targaryen heirs Aegon and Rhaenyra all but guaranteeing plenty of big battle scenes and expensive CGI dragons.

Condal also recently revealed to Josh Horowitz on the Happy Sad Confused podcast that the third season will see an experimental episode that will be more "conceptual" and "character-driven" installment than "HOTD" fans have seen from the HBO fantasy series so far.

“We got to have a little fun this season, and there’s a conceptual episode that I’m really excited about that [Sara Hess] wrote, and that’s all I’m gonna say about it," Condal revealed. "It isn’t in the traditional vernacular of what we have laid out. It’s very character-driven, I think it’s really great and I’m really excited to see it rendered.” Ditto!
