Alright, House of the Dragon fans, let’s talk about Season 3! After that jaw-dropping Season 2 finale, we’re all itching to know what’s next for the Targaryens and their dragon-filled civil war. The internet’s buzzing with rumors, leaks, and fan theories, so let’s dive into the latest on release dates, who’s in the cast, and what we can expect from the next chapter of this Game of Thrones prequel.
House of the Dragon Season 3 Potential Release Date
HBO’s keeping the official release date for Season 3 under wraps, which is honestly driving us nuts. But here’s what we’ve pieced together. Filming kicked off in March 2025 at Warner Bros. Studios Leavesden in the UK, with some extra shoots in Wales and the Canary Islands. Those dragon battles and fancy CGI take a ton of time to polish—think nine months to a year for post-production.
Looking at the gap between Seasons 1 and 2 (about two years), most folks are betting on a mid-to-late 2026 premiere, probably around June to September.
House of the Dragon Season 3 Cast Updates
Season 3’s bringing back the heavy hitters from Season 2, assuming they didn’t get torched or betrayed in the finale. Here’s who we expect to see:
-
Emma D’Arcy as Rhaenyra Targaryen
-
Olivia Cooke as Alicent Hightower
-
Matt Smith as Daemon Targaryen
-
Tom Glynn-Carney as Aegon II Targaryen
-
Ewan Mitchell as Aemond Targaryen
-
Plus, fan favourites like Rhys Ifans (Otto Hightower), Steve Toussaint (Corlys Velaryon), Fabien Frankel (Ser Criston Cole), and others like Harry Collett, Bethany Antonia, Phoebe Campbell, Phia Saban, and Sonoya Mizuno.
And here’s the exciting part—new faces! The show’s adding some cool characters to shake things up:
-
James Norton (Little Women, Happy Valley) as Ormund Hightower, Alicent’s cousin and a big-shot lord from Oldtown, rolling in with his dragon-riding nephew, Daeron Targaryen.
-
Tommy Flanagan (Sons of Anarchy) as Ser Roderick Dustin, aka “Roddy the Ruin,” a tough northern knight leading the Winter Wolves.
-
Dan Fogler (Fantastic Beasts) as Ser Torrhen Manderly, another northern badass joining the fight.
What to expect in House of the Dragon Season 3
Season 3’s diving headfirst into the Dance of the Dragons, and it’s gonna be chaos. If you’ve read Fire & Blood, you know we’re in for some wild times. Word is, the season’s kicking off with the Battle of the Gullet, a massive naval showdown that’s one of the bloodiest fights in Westeros history. Rhaenyra’s new dragonriders versus the Triarchy’s fleet? Buckle up. Ryan Condal’s already hyping it, saying the war’s gonna “heat up fast” with some epic battle scenes.
