'House of the Dragon' season 3: Everything we know so far

"House of the Dragon" season 2 has been and gone, and the wait for "House of the Dragon" season 3 is on.

Whether or not you agree that you feel somewhat cheated by the "House of the Dragon" season 2 finale, one thing's for sure: the stakes are higher than ever, and some serious action is all but guaranteed when one of the best Max shows returns to our screens.

The rest of George R.R. Martin's "Fire & Blood" contains some spectacular, brutal battles, and, off the back of how exciting the Battle of Rook's Rest was to watch, I cannot wait for "House of the Dragon" season 3 to bring the rest of the story to life on HBO and HBO Max.

Here's what we know about "House of the Dragon" season 3 right now.

'House of the Dragon' season 3 release date speculation

As of our latest update, we don't have a "House of the Dragon" season 3 release date, and I wouldn't be surprised if we don't get one for a while yet, either.

We've known that the show would be returning for a while; HBO confirmed two more seasons of "House of the Dragon" would be on the cards in June 2024.

Production on the penultimate season finally got underway on season 3 in Hertfordshire, England and in North Wales back in March, nine months after the season 2 finale roared onto HBO Max.

We waited two years between seasons 1 and 2 and, seeing as we're expecting to see "A Knight of the Seven Kingdoms" first, and that other, smaller-in-scope "Game of Thrones" spinoff has been delayed to 2026, I'm a little worried that the wait for "House of the Dragon" to return could maybe be even longer.

Who's in the 'House of the Dragon' season 3 cast? 

Although we don't know for sure, we'd expect most of the ensemble cast to return for "House of the Dragon" season 3.

Barring those who have already lost their lives in the Dance of the Dragons thus far — no, I'm still not over Rhaenys' death — everyone's got a part to play in the ensuing conflict, one way or another.

Here's a list of just some of the main stars we're convinced will make an appearance in the third season:

• Emma D'Arcy as Rhaenyra Targaryen
• Olivia Cooke as Alicent Hightower
• Matt Smith as Daemon Targaryen
• Ewan Mitchell as Aemond Targaryen
• Phia Saban as Helaena Targaryen
• Tom Glynn-Carney as Aegon II Targaryen
• Harry Collet as Jacaerys Velaryon
• Steve Toussaint as Corlys Velaryon
• Bethany Antonia as Baela Targaryen
• Phoebe Campbell as Rhaena Targaryen
• Rhys Ifans as Otto Hightower
• Matthew Needham as Lord Larys Strong
• Gayle Rankin as Alys Rivers
• Clinton Liberty as Addam of Hull
• Abubakar Salim as Alyn of Hull
• Kieran Bew as Hugh Hammer
• Tom Bennett as Ulf the White
• Sonoya Mizuno as Mysaria
• Jefferson Hall as Jason and Tyland Lannister
• Tom Taylor as Lord Cregan Stark

At the end of January, we also learned (via Variety) that British actor James Norton had boarded the show as Ormund Hightower.

Ormund is Otto's nephew and the current Lord of Oldtown. In the show, he's currently leading the Hightower forces to King's Landing to bolster the Greens' defences against Rhaenyra's allies.

Condal called Norton's casting "the biggest new role that I think we've added since season 1," adding, "I think that Ormund is really going to delight and surprise the audience with what he brings to the narrative and with what James does with the character."

In April 2025, we learned the identities of some new cast members, too. Per Entertainment Weekly, we learned "Sons of Anarchy" and "Peaky Blinders" star Tommy Flanagan had joined "House of the Dragon" to play Ser Roderick Dustin, or "Roddy the Ruin."

EW further confirmed that actor-comedian Dan Fogler has joined the show as a knight known as Ser Torrhen Manderly.

'House of the Dragon' season 3 plot

While exact plot details will no doubt stay under wraps for quite some time just yet (yes, OK, you could look ahead in the original book, but we won't do that here), all signs point to all-out war in "House of the Dragon" season 3.

Both the Greens and Blacks spent season 2 attempting to bolster their forces in one way or another, and in the season finale's final moments, both sides braced for conflict, and their forces began to march off to war.

Rhaenyra's faction might have suffered a blow after Aemond and Vhagar defeated Rhaenys and Meleys, but they've since gained three new dragonriders, and Daemon renewed his vow to Rhaenyra and showed he'd managed to raise a huge army at Harrenhal.

After waging more of a successful ground campaign, the Greens were on the back foot, though Tylan Lannister has at least secured an allegiance with the Triarchy, which might mean they can break Corlys' naval blockade in the Gullet.

Is 'House of the Dragon' season 3 the show's last? 

Mere hours after writing this article, we learned that "House of the Dragon" would run for four seasons.

At a press conference discussing the season 2 finale, showrunner and co-creator Ryan Condal confirmed that the "Game of Thrones" prequel would conclude with season 4.

We don't yet know whether the series will also be another eight-episode run; when asked, he said: "I haven't had discussions with HBO about it. I would just anticipate the cadence of the show, from a dramatic storytelling perspective, will continue to be the same from season 2 on' (via Variety).

News that the spinoff will end with season 4 isn't too surprising. After all, George R.R. Martin claimed on his 'Not a Blog' site that 'it is going to take four full seasons of 10 episodes each to do justice to the Dance of the Dragons, from start to finish' back in 2022. So, apart from the fact that we switched to a shorter second season, it sounds like things are progressing more or less according to plan.

This also means we could be on for some seriously explosive final seasons, as some of the Dance of the Dragons' bloodiest battles take place further down the timeline.
