When you think about the power players in Westeros, most people jump straight to the dragons or the ice zombies. But for five seasons, the real threat to the status quo didn't carry a sword. She carried a smile. If you’re wondering who plays Margaery Tyrell, the answer is Natalie Dormer, an actress who basically redefined what it looks like to be a "strong female character" in fantasy TV.
Honestly, she wasn't just playing a role; she was performing a high-wire act.
The Face Behind the Tyrell Rose
Natalie Dormer stepped into the shoes of Margaery Tyrell back in Season 2. Before she arrived, the character in George R.R. Martin’s books was a bit of a mystery—younger, quieter, and mostly seen through the eyes of other people who didn't really trust her.
Dormer changed that immediately.
She brought this specific kind of sharp, knowing energy to the screen. You’ve probably seen her "smirk"—it’s legendary. It’s that half-smile that says she knows exactly what you’re thinking, and she’s already three steps ahead of you.
Born in Reading, Berkshire, Dormer wasn't exactly a newcomer when she landed the gig. She had already made a massive splash in The Tudors playing Anne Boleyn. It’s funny because Anne and Margaery are basically cousins in terms of personality. Both were ambitious, both were smarter than the kings they married, and—spoiler alert—both met pretty grim ends because they played the game a little too well.
Why Natalie Dormer Was the Perfect Margaery
Casting is everything. If the producers had gone with someone who played Margaery as a purely "good" girl, the character would have been boring. If they made her a pure villain, she would have been another Cersei.
Dormer found the middle ground.
She played the "Kate Middleton" of Westeros
In interviews, Dormer often described Margaery as a sort of modern politician or a royal like Kate Middleton. She understood that power in King’s Landing didn't just come from fear; it came from PR.
While Cersei was busy drinking wine and threatening to burn cities down, Dormer’s Margaery was out in the mud with the peasants. She was visiting orphanages. She was feeding the poor.
Was it genuine? Sorta. Was it a calculated move to make the people love her so much that the Lannisters couldn't touch her? Absolutely. Natalie Dormer played that ambiguity perfectly. You never quite knew if she actually cared about the orphans or if she was just counting the "likes" she’d get on her medieval Instagram.
The chemistry with the cast
One of the best parts of watching Natalie Dormer as Margaery Tyrell was seeing her go toe-to-toe with the heavy hitters.
- The Olenna Dynamic: Her scenes with Diana Rigg (who played the Queen of Thorns) felt like a masterclass. You could see the grandmother teaching the granddaughter how to sharpen her claws.
- The Cersei Rivalry: The tension between Natalie Dormer and Lena Headey was so thick you could cut it with a Valyrian steel blade. It was a cold war fought with polite insults and fake smiles.
- The Joffrey/Tommen Situation: Let’s be real—managing Joffrey Baratheon was like trying to pet a rabid wolverine. Dormer made it look easy. She switched from being a seductive queen to a motherly figure for Tommen without missing a beat.
Life Before and After King’s Landing
If you only know her from Game of Thrones, you’re missing out.
Natalie Dormer has a range that’s actually kind of wild. She went from the corsets of The Tudors to the shaved head and combat boots of The Hunger Games: Mockingjay, where she played Cressida.
She’s also done:
- Elementary: Playing a very "Dormer-esque" version of Irene Adler (and Moriarty).
- Penny Dreadful: City of Angels: Where she played four different characters. Seriously, four.
- In Darkness: A psychological thriller she actually co-wrote.
She’s always been vocal about the fact that she doesn't just want to play "the girlfriend." She wants roles with agency. Even in Captain America: The First Avenger, where she had a tiny role as Private Lorraine, she made sure people remembered her.
What Happened to Margaery? (The Sept of Baelor)
We have to talk about the exit.
In Season 6, the story of Margaery Tyrell came to an explosive end. It’s one of the most famous scenes in TV history. Cersei blows up the Great Sept of Baelor with wildfire, killing basically everyone inside.
What made that scene work—the reason it still hurts to watch—is Natalie Dormer’s performance in those final seconds.
Margaery is the only person in that room smart enough to realize something is wrong. She sees that Cersei isn't there. She sees the High Sparrow’s arrogance. She tries to get everyone out. That look of pure, realization-drenched terror on her face right before the green flames hit? That’s why people are still Googling "who plays Margaery Tyrell" years after the show ended.
She was the smartest person in the room, and it still wasn't enough.
Natalie Dormer’s Impact on the Fandom
Even now, fans debate whether Margaery was a hero or a manipulator.
The truth is she was both. Natalie Dormer gave us a character who was unapologetically ambitious but also fundamentally more "human" than most of the people she shared the screen with. She wasn't a warrior, but she was a fighter.
She used the tools available to women in a patriarchal, violent world—charm, intelligence, and family loyalty—and she almost won.
Where Can You See Her Now?
If you’ve got a Margaery-shaped hole in your heart, Natalie Dormer is still very much active. She’s moved into producing and writing while continuing to take on complex roles in film and theater.
In 2024, she starred in the dark thriller The Wasp, which is about as far from the gardens of Highgarden as you can get. It’s gritty, intense, and shows off those acting chops that made us fall in love with the Tyrells in the first place.
Keep an eye on these Natalie Dormer projects if you want more of her specific brand of screen presence:
- The Tudors (For the ultimate "Margaery-in-training" vibes).
- Picnic at Hanging Rock (She plays a stern headmistress, totally different vibe).
- The Wasp (Her latest 2024/2025 psychological drama).
If you want to dive deeper into the world of Westeros, your best bet is to re-watch Seasons 2 through 6 of Game of Thrones. Pay close attention to the background of her scenes; Natalie Dormer often does more with a side-eye or a slight adjustment of her dress than most actors do with a five-minute monologue.
Check out some of her "Inside the Episode" interviews on YouTube to hear her talk about the psychology of the character. It’s fascinating stuff.
Next Steps for the Super-Fan: Go watch the Season 6 finale again, but this time, only watch Natalie Dormer's eyes. You'll see the exact moment she realizes the game is over. Once you've done that, look up her performance in Elementary to see how she handles a modern-day genius role. It's a total trip.
