Everyone thinks they know her. That’s the problem. When you ask who plays Princess Diana, you aren’t just asking for a list of names on an IMDB page; you’re asking who managed to capture that specific, lightning-in-a-bottle mix of vulnerability and star power. It’s a terrifying gig. Actors don't just take on a role here—they take on a ghost that half the world still feels protective of.
Honestly, casting Diana Spencer is basically a high-stakes gamble for any production. If the chin tilt is off by two degrees, the internet notices. If the posh-but-breathy "Sloane Ranger" accent sounds too much like a caricature, the performance tanks. We’ve seen a massive surge in portrayals recently, mostly because the 25th anniversary of her passing and the conclusion of The Crown put her back into the cultural blender.
The Crown and the Evolution of Diana
Netflix didn't just cast one person; they needed a timeline. They needed to show the transition from "Shy Di" to the global icon in the revenge dress.
Emma Corrin’s Breakthrough
When Emma Corrin stepped onto the screen in Season 4, she was a relative unknown. That worked in her favor. You saw this teenage girl with the side-swept bangs who looked genuinely overwhelmed by the flashbulbs. Corrin nailed the physicality—that specific way Diana looked up through her lashes. It wasn’t just an impression; it felt like an exploration of how a person gets swallowed by an institution. Critics at The Guardian and The New York Times largely agreed that Corrin captured the "doe-eyed" innocence that the public fell in love with in 1980.
Elizabeth Debicki’s Masterclass
Then came the pivot. Elizabeth Debicki took over for Seasons 5 and 6, and suddenly, the height mattered. Diana was tall. She occupied space. Debicki is nearly 6'3", and she used that height to show a woman who was trying to fold herself small while also becoming a giant on the world stage. It’s arguably the most "accurate" portrayal we’ve ever seen. She got the voice—that low, melodic, slightly hesitant cadence—down to a science.
The fascinating thing about Debicki's turn as the woman who plays Princess Diana is how she handled the 1995 Bashir interview. It was meta. A famous woman playing a famous woman being famous. It was heavy.

Kristen Stewart and the Experimental Shift
Then there's Spencer. Pablo Larraín’s 2021 film wasn't a biopic. It was a horror movie set in a drafty castle. When it was announced that Kristen Stewart would be the one who plays Princess Diana, people lost their minds. "An American? Playing the Princess of Wales?"
It felt wrong to the traditionalists.
But Stewart leaned into the alienation. She didn't try to look exactly like her. Instead, she captured the internal vibrating anxiety of a woman who feels like she’s being hunted. It was twitchy. It was sweaty. It was claustrophobic. Stewart eventually landed an Oscar nomination for it, proving that sometimes, capturing the vibe of a person is more important than being a lookalike. She focused on the rebellion. The way Diana used her clothes as armor.
The Ones We Kind of Forgot (But Shouldn't)
Long before Netflix had a billion-dollar budget, other actresses took a stab at the crown. Some hit the mark; others missed by a mile.
- Naomi Watts in Diana (2013): This is usually cited as the cautionary tale. Watts is a powerhouse, but the script was focused on Diana’s relationship with Hasnat Khan. It felt like a Lifetime movie with a theatrical budget. The lesson here? You can’t just put a blonde wig on a talented actress and expect magic. The soul has to be there.
- Jeanna de Waal in Diana: The Musical: Look, the filmed version on Netflix is... a lot. It’s campy. It’s strange. But playing Diana on a Broadway stage requires a different set of lungs. It was less about nuance and more about the "iconography."
- Serena Scott Thomas: Way back in 1993, while Diana was actually still alive and the divorce was the hottest gossip on the planet, Scott Thomas played her in Diana: Her True Story. It was based on the Andrew Morton book. It's dated now, sure, but at the time, it was scandalous.
Why Is This Role So Hard to Cast?
It’s the "Diana Look." It’s a combination of 1980s blue eyeliner, a very specific haircut that changed the hair industry forever, and an energy that felt accessible yet royal.

Casting directors like Robert Sterne (who worked on The Crown) have talked about how they looked for an "inner quality." You can't just act "royal." You have to act like someone who is bored by being royal but trapped by it.
The Physicality Factor
Most actresses struggle with the "Diana Tilt."
- The Head Down: Used to hide from paparazzi.
- The Upward Gaze: Used to connect with people.
- The Long Stride: She walked like an athlete, not a pageant queen.
If an actor misses these beats, the audience disconnects immediately. We've seen too much footage of the real Diana to be fooled by a mediocre imitation. We are all experts on her face because she was the most photographed person in history. That is a brutal reality for anyone who plays Princess Diana.
The Impact of the Portrayal on the Royal Family
We can't talk about these performances without acknowledging the real-world tension. Prince Harry mentioned in his memoir, Spare, that he’s aware of these depictions. The line between entertainment and history is incredibly blurry here. When Elizabeth Debicki portrays the final days in Paris, it isn't just "content" for the people who actually lived through it.
It’s a strange phenomenon. These actresses end up becoming the "face" of Diana for a new generation that wasn't alive in 1997. If you ask a 20-year-old today who Diana is, they might picture Emma Corrin before they picture the actual woman. That’s a massive responsibility for a performer.

What to Watch Next
If you're trying to decide which performance is worth your time, it depends on what you're looking for.
If you want the historical sweep and the most realistic transformation, watch Elizabeth Debicki in The Crown Seasons 5 and 6. She spent months working with movement coaches and dialect experts. It shows. Every sigh feels authentic.
If you want the emotional internal wreck, go for Kristen Stewart in Spencer. It’s a tone poem. It’s weird. It’s artistic. It’s not "accurate" in terms of events, but it’s very accurate in terms of the pressure of the Royal family.
If you want the fairytale-turned-nightmare, Emma Corrin in The Crown Season 4 is the gold standard. You see the transition from a girl living with roommates in Earl's Court to a woman realizing she’s married into a cold, stiff world.
Actionable Insights for Fans and Researchers
Don't take any single portrayal as the absolute truth. Every director has an agenda. Every screenwriter wants a specific narrative arc.
- Cross-Reference: If a scene in a movie feels too dramatic to be true, check the historical record. Use sites like The Diana Chronicles by Tina Brown for a more grounded look at the events depicted on screen.
- Watch the Real Footage: Go back to the 1995 Panorama interview or the footage of her walking through the minefields in Angola. See how the actresses mirrored those movements.
- Ignore the Makeup: Focus on the eyes. The best actresses who play Princess Diana are the ones who can convey her "active listening" style—the way she made people feel like they were the only person in the room.
The obsession with Diana isn't going away. As long as there is a fascinaton with the British Monarchy, there will be a new actress stepping into those sapphire engagement ring shoes. Each one adds a new layer to the legend, for better or worse. Whether it’s the grace of Debicki or the grit of Stewart, they all prove one thing: Diana is a role that can never truly be "finished."
The next time a casting announcement drops for a new project, expect the same cycle of skepticism and eventual obsession. It’s just the way it goes with the most famous woman in the world. Look for the nuance, not just the wig. That's where the real story lives.
