James Norton Is Already Stealing ‘House of the Dragon’ Season 3 as the Greens’ Most Dangerous New Wildcard

‘House of the Dragon‘ has never been shy about dropping bombshell casting decisions, but the addition of James Norton to its already stacked ensemble feels like a different kind of announcement. Season 3 of the HBO dragon epic is barely underway, and one newcomer is already making everybody forget they ever had questions about the show’s direction.

Norton arrives as Ormund Hightower, a figure teased throughout Season 2 but never shown on screen, and the wait appears to have been very much worth it. Critics and fans alike have already zeroed in on the character as one of the most exciting new presences in the season, with Variety calling him a genuine “chaos agent” who enters the conflict with his own agenda and strategy.

James Norton’s Casting Brings a BAFTA-Nominated Career to Westeros

Norton is perhaps best known for his roles in the British TV shows ‘Happy Valley’ and ‘Grantchester,’ though he has also starred in series such as ‘McMafia’ and the 2016 miniseries adaptation of ‘War and Peace,’ and he received a BAFTA nomination in 2015 for his role in ‘Happy Valley.’ That pedigree matters enormously when a show like ‘House of the Dragon’ takes a risk on a character who is essentially a footnote in the source material.

Norton served as executive producer on the BBC historical drama ‘King and Conqueror,’ where he played Harold Godwinson, a series produced by Norton’s own production company that aired on BBC in August 2025. He came to ‘House of the Dragon’ fresh off that kind of creative authority, which perhaps explains why he walks into Westeros looking entirely at home.

In an exciting first look at filming in the Surrey countryside, Norton was pictured in full costume dressed in his house’s signature colours of muted greens and silvers, spotted alongside Matt Smith in scenes that appear to show Ormund surrendering his sword to Daemon Targaryen, though whether the moment represents surrender or alliance remains unclear. Whatever side of that debate lands, it is clear the showrunners built this character with Norton specifically in mind.

Ormund Hightower and His Place in the Hightower Family Tree

Ormund was referenced in Season 2 but never appeared on screen, and he is Otto’s nephew, Alicent and Gwayne’s cousin, and the Lord of Oldtown, presently leading the Hightower host in a march on King’s Landing to support his house against Rhaenyra. That family positioning gives him enormous weight within the Green faction without requiring any dragon-riding entrance to prove it.

As the commander of one of the biggest and wealthiest armies in the Seven Kingdoms, Ormund’s support is a huge win for the Greens, and perhaps more importantly, he has protected and mentored Daeron Targaryen all this time, with the young prince’s dragon Tessarion set to play a major role as the war expands.

In his first scene in the Season 3 premiere, Ormund is stationed on the battlefield receiving a letter from King Aemond telling him to wait for orders, and he seems unaccustomed to the dirtier side of war, struggling with the scent of a messenger while being quietly thrilled by the news that Aemond is now king. It is exactly the kind of character detail that separates a well-crafted antagonist from a generic warlord.

Ormund leads the Hightower army of 15,000 men through the Reach, aiming to reinforce the defence of King’s Landing in conjunction with the arrival of the Triarchy fleet from Essos. The numbers alone make him one of the most consequential figures on the board heading into this season’s central conflicts.

The Showrunner’s Vision for a ‘Fire and Blood’ Sketch Turned Scene-Stealer

Showrunner Ryan Condal described Ormund to SFX magazine as “basically the Tywin Lannister of this world,” explaining that he is “the richest guy who’s not sitting on a throne somewhere,” with the largest standing army left in Westeros and a dragon to back it up. Framing a new character through the lens of one of the most beloved figures in the entire ‘Game of Thrones’ universe is a bold but clearly intentional move.

Condal also acknowledged that “Ormund is really a sketch in the book and we don’t have a sense of who he is, so it was really fun diving in and creating a really deep, complex and three-dimensional character out of him that introduces a new kind of complication into the world.” That creative latitude is what distinguishes ‘House of the Dragon’ at its best from a straightforward page-to-screen adaptation.

Variety described Ormund as “deceptive, capricious, fussy and endowed with quirks like a sensitivity to scents,” noting that he enters the conflict nominally allied with the Greens but pursuing an agenda and strategy distinctly his own. That tension between family loyalty and personal ambition is the kind of friction that fuels the best performances in this entire franchise.

Fan Reactions and Critical Praise for the Season 3 Newcomer

Following the Season 3 premiere, fans on Reddit were already declaring their allegiance to the Ormund storyline, with one viewer writing “He’s awful, I love it,” and another stating they had “no clue who he is cause I haven’t read the book but this actor nailed the pompous elitist high born facial expressions” in what amounted to barely a two-minute scene.

Critics were equally effusive, with Fangirlish writing that “without a doubt, James Norton’s Ormund Hightower” was the standout of the new season, describing a “magnetism to his every moment on screen that makes it hard to look away, whether you are rooting for him or not,” while CBR noted that “the Greens were in desperate need for a megalomaniac, acidic character like Ormund.”

The Hollywood Reporter’s Daniel Fienberg also singled out Norton’s performance as Ormund Hightower as one of the best among all the season’s cast newcomers, even amid broader observations about the show having perhaps too much on its plate heading into its final stretch. That kind of critical consensus in the very first week of a season is not something that happens by accident.

One fan perhaps put it most concisely, saying they were “just over the moon to see James Norton in Westeros” because “he’s such an amazing actor,” while another was sold on the character the moment he delivered the line “King, is he now?” accompanied by what they described as the perfect “hoity-toity face.”

If Ormund Hightower can inspire that kind of reaction in a single brief scene, Westeros may have just found its most compelling new villain of the entire run of the show, and it would be fascinating to hear which moment from his debut already has you convinced.
