HBO’s second year in Westeros was a gamble. Honestly, everyone remembers the dragons and the massive "Blackwater" explosion, but that's not why the show became a global behemoth. It happened because of the people. Specifically, the actors in Game of Thrones Season 2 had to carry the weight of a world that was suddenly getting much, much bigger.
The first season had Sean Bean to lean on. He was the anchor, the big name, the guy on the poster. Then, they killed him.
By the time the premiere of The North Remembers rolled around in April 2012, the casting directors—shoutout to Nina Gold, who is basically a genius—had to find a way to fill that vacuum. They didn't just need bodies; they needed gravitas. This was the year of the "Five Kings." It was a mess of competing egos, and if the actors didn't sell the desperation, the whole thing would have collapsed into a cheesy Renaissance fair.
The Newcomers Who Changed Everything
You can’t talk about the sophomore slump (which this show avoided) without mentioning Stephen Dillane. As Stannis Baratheon, Dillane was... intense. I’ve heard rumors he didn't even fully understand the plot half the time while filming, but maybe that’s why it worked? He played Stannis with this rigid, grinding teeth frustration that felt incredibly real. He wasn’t a "fantasy" hero. He was a disgruntled middle manager with a claim to the throne and a very scary red-headed priestess behind him.
Then there was Carice van Houten as Melisandre.
She brought this eerie, quiet confidence that shifted the show's tone from "political thriller with knights" to "something supernatural is actually happening." Most actors would have chewed the scenery playing a shadow-birthing witch. She didn't. She was cold. Calculating.
And we have to talk about Liam Cunningham as Davos Seaworth. If Stannis was the iron, Davos was the heart. Cunningham’s chemistry with Dillane is basically the only reason those Dragonstone scenes didn't feel like a chore. He gave us a POV character who was actually a "good" man, which was a rare commodity in 2012.
Gwendoline Christie and the Physicality of Brienne
Finding Brienne of Tarth was supposed to be impossible. George R.R. Martin wrote a character who was exceptionally tall, incredibly strong, and "unconventionally" looking. Gwendoline Christie didn't just fit the description; she inhabited the trauma of the character.
Her introduction in Season 2, beating Ser Loras Tyrell in a tourney, changed the gender dynamics of the show instantly. You saw the vulnerability in her eyes when Renly Baratheon spoke to her. It wasn't just about being a warrior; it was about the desperate need to belong. Christie reportedly went through a massive physical transformation for the role, losing weight and gaining muscle to strip away her natural "feminine" gait. It paid off.

The Evolution of the Season 1 Veterans
While the new faces were great, the actors in Game of Thrones Season 2 who were already there had to level up.
Peter Dinklage.
He won an Emmy for Season 1, sure, but Season 2 is where Tyrion Lannister became the protagonist of the entire series. This was the "Acting Hand of the King" era. Dinklage played Tyrion with a mix of newfound power and deep-seated fear. The scenes where he faces off against Lena Headey (Cersei) are like watching a masterclass in subtext. They hate each other, but they’re the only ones in the room who are actually smart enough to know how much trouble they're in.
Headey is also doing some of her best work here. In Season 2, Cersei starts to lose control of her son, Joffrey. You see the cracks. She’s drinking more. She’s terrified. It’s not just "villain" acting; it's a portrait of a mother realizing she’s created a monster she can’t leash.
Jack Gleeson’s Burden
Spare a thought for Jack Gleeson.
He played Joffrey Baratheon so well that people actually harassed him in the streets. That’s a testament to the kid’s talent, even if it’s a bit sad. In Season 2, Joffrey goes from a spoiled brat to a genuine sadistic tyrant. The scene with the crossbow and the two girls Tyrion sent to his room? Horrifying. Gleeson managed to make Joffrey look simultaneously pathetic and dangerous. Most actors can only do one of those.
Why the Casting Matters for SEO and History
When you look back at the actors in Game of Thrones Season 2, you’re looking at a turning point in television history. This was the season that proved you could have an "ensemble" cast where twenty different storylines actually mattered.
Think about Alfie Allen as Theon Greyjoy.

His arc in Season 2 is arguably the most complex. He goes home, gets rejected by his father, betrays the Starks, and tries to hold Winterfell with a handful of guys who don't respect him. Allen plays it with this shaky, desperate bravado. You hate him for what he does to Bran and Rickon (or what we think he does), but you also feel that pathetic need for approval. It’s a messy, human performance.
- Stannis Baratheon (Stephen Dillane): The rigid, unyielding claimant.
- Melisandre (Carice van Houten): The fanatical catalyst for the supernatural.
- Davos Seaworth (Liam Cunningham): The moral compass of the series.
- Brienne of Tarth (Gwendoline Christie): The breaker of gender norms.
- Margaery Tyrell (Natalie Dormer): The introduction of a new kind of political savvy.
Dormer’s introduction as Margaery was a masterstroke. She didn't play her as a victim of her marriage to Renly. She played her as someone who wanted to be The Queen. It was a huge departure from the books' younger version of the character, and it gave the show a new power player that resonated with audiences.
The Technical Reality of Filming Season 2
It wasn't all just "acting."
The cast had to endure miserable conditions. The scenes in the North (actually filmed in Iceland) were brutal. Kit Harington (Jon Snow) and Rose Leslie (Ygritte) were out there in sub-zero temperatures. That "chemistry" people talk about? Part of it was probably just trying to stay warm. Rose Leslie’s "You know nothing, Jon Snow" became a cultural phenomenon, but in Season 2, she was just a spark of life in a very cold, grey storyline beyond the Wall.
Then there’s the mud.
The Battle of the Blackwater was filmed over many cold nights in Belfast. The actors were soaked, covered in fake blood and grime, and swinging heavy props. When you see Rory McCann (The Hound) looking like he’s about to have a panic attack because of the fire, that’s not just talent. That’s a man who has been filming in the dark for weeks on end.
Emilia Clarke’s Struggle in Qarth
While everyone else was fighting in the mud, Emilia Clarke was stuck in "Qarth." A lot of fans think the Qarth storyline is the weakest part of Season 2. Honestly? They might be right. But Clarke had to carry that entire plot on her back with mostly just her dragons (which weren't there, they were tennis balls on sticks) and a few supporting actors like Nonso Anozie (Xaro Xhoan Daxos).
She had to sell the "Mother of Dragons" persona before she actually had the power to back it up. It’s a performance of "fake it 'til you make it," which fits Daenerys’s journey perfectly at that stage.

The Legacy of the Season 2 Cast
Most of these actors weren't household names in 2012.
Now? They’re everywhere. Maisie Williams and Sophie Turner were literally growing up on screen. In Season 2, Arya’s scenes with Charles Dance (Tywin Lannister) are legendary. Those scenes weren't even in the books! The producers saw the chemistry between a veteran like Dance and a kid like Williams and just let it happen. It’s some of the best dialogue in the whole series.
Actionable Insights for Fans and Rewatchers:
- Watch the eyes: In Season 2, pay attention to Tyrion’s eyes when he’s talking to Shae. The vulnerability Dinklage shows is what makes his eventual "betrayal" in later seasons so painful.
- Theon's body language: Notice how Alfie Allen’s posture changes when he’s at Winterfell versus when he’s on the ship with his sister, Yara. He’s a different person depending on who he’s trying to impress.
- Background players: Keep an eye on Tom Wlaschiha as Jaqen H'ghar. His physical acting—the way he moves and speaks in the third person—set the stage for the entire Braavos storyline years later.
If you’re going back to watch, don't just look for the dragons. Look at the faces of the actors in Game of Thrones Season 2. They were the ones who turned a niche fantasy book series into a cultural titan. They made the stakes feel real when the CGI couldn't quite do the heavy lifting yet.
The brilliance of the casting in this specific season is why the show lasted as long as it did. They built a foundation of characters you actually cared about, even if you wanted to see half of them get slapped (looking at you, Joffrey).
To truly appreciate the craft, compare the "Blackwater" performances to any modern big-budget streaming show. There’s a grit and a commitment in the Season 2 cast that is incredibly hard to replicate. They weren't just playing roles; they were surviving Westeros.
Practical Next Steps for Your Rewatch:
- Focus on the Harrenhal scenes: Specifically the dialogue between Arya and Tywin. It’s the gold standard for character-driven writing and acting.
- Track Stannis’s descent: Watch how Stephen Dillane slowly lets Melisandre’s influence erode his rigid sense of justice.
- Appreciate the "small" moments: Like Bronn (Jerome Flynn) and Tyrion’s banter. It’s the heartbeat of the King’s Landing scenes.
