If you’ve watched "A Scandal in Belgravia," you know the feeling. That moment when a character walks into a room and completely hijacks the entire series. When people ask who plays Irene Adler in Sherlock, the answer is technically a matter of public record, but the performance itself is something much more complex than a simple IMDB credit.
Lara Pulver.
She’s the one. She took a character from a 19th-century short story and turned her into a modern-day powerhouse that left Benedict Cumberbatch’s Sherlock Holmes—and most of the audience—breathless. It wasn't just about the "battle dress" (or the lack thereof). It was about a specific kind of intellectual ferocity that most actors just can't pull off without looking like they're trying too hard. Pulver didn't try. She just was.
The Performance That Redefined the Woman
Before Lara Pulver stepped into the role in 2012, Irene Adler had been played by dozens of women. We had Rachel McAdams in the Guy Ritchie films, who was great, but felt a bit more like a traditional action heroine. We’ve had classical interpretations that stayed very close to the Victorian opera singer roots. But Steven Moffat and Mark Gatiss wanted something different for the BBC version. They needed someone who could outthink Sherlock Holmes.
Pulver was essentially a theater veteran before this role catapulted her into the global spotlight. She had been nominated for an Olivier Award for her work in Parade and had appeared in True Blood and Spooks. But Sherlock was a different beast.
Honestly, the chemistry between her and Cumberbatch is what makes that episode the highest-rated of the entire series for many fans. It wasn't just romantic; it was predatory. It was a game of chess played with pulse rates and pupils. When you look at who plays Irene Adler in Sherlock, you aren't just looking for an actress; you're looking for the only person who ever truly beat Sherlock at his own game, even if the ending of the episode remains a point of massive debate among fans.
Why the Casting Almost Didn't Work
Casting a character as iconic as "The Woman" is a nightmare for a production team. If you go too young, she doesn't have the gravitas. If you go too "femme fatale," she becomes a cliché.
The creators needed someone who could deliver lines like "I'd have you on this table until you begged for mercy" without it sounding like a cheap B-movie. Pulver has this incredible ability to use her voice as a precision instrument. It’s low, steady, and terrifyingly confident.

There were rumors at the time that other high-profile British actresses were considered, but once Pulver did her chemistry read, it was over. Gatiss has mentioned in interviews that they needed someone who felt like a "match" for Sherlock’s alien-like intellect.
Beyond the Screen: Who is Lara Pulver?
It’s easy to get lost in the character and forget the actor. Lara Pulver is a powerhouse. Born in Southend-on-Sea, she grew up with a deep background in dance and musical theater. This is actually a huge reason why her Irene Adler is so physical.
Think about the way she moves. It’s choreographed.
Every tilt of the head, every placement of a hand—it’s the work of someone who understands how to command a stage. Since Sherlock, she hasn't just sat around waiting for another Irene Adler-sized role. She won an Olivier Award in 2016 for her role as Louise in the West End revival of Gypsy. She’s also voiced Princess Mirana in DOTA: Dragon's Blood and starred in The Split.
But for a specific subset of the internet, she will always be the woman who knew Sherlock’s measurements just by looking at him.
The Controversy of the Character
We have to talk about the backlash. Not everyone loved this version of Irene. Some critics argued that turning a "prima donna" from the original Arthur Conan Doyle stories into a professional dominatrix was a bit much. They felt it stripped away her agency by making her eventually need Sherlock to "save" her in Karachi.
But Pulver defended the role. She saw Irene as a woman who owned her sexuality and used it as a weapon in a world dominated by men like Mycroft and Moriarty. Whether you agree with the writing or not, you can't deny the commitment Pulver brought to it. She didn't play a victim. She played a queen who made a single, human mistake.

How the BBC's Irene Adler Compares to Others
If you're wondering who plays Irene Adler in Sherlock compared to other versions, the landscape is actually pretty crowded.
- Rachel McAdams (Sherlock Holmes 2009): More of a thief and a rogue. Charming, but definitely a different vibe.
- Natalie Dormer (Elementary): This was a wild twist. In the CBS show Elementary, Irene Adler turns out to be [SPOILER] Jamie Moriarty. Dormer is fantastic, but the role is more about villainy than the specific intellectual flirtation Pulver mastered.
- Charlotte Rampling (Sherlock Holmes in New York): A more classic, dignified take from the 70s.
Pulver’s version remains the most "viral." Her introduction—walking into the room completely naked to disarm Sherlock’s "deduction" powers—is one of the most famous scenes in 21st-century television. It was a literal blank slate. He couldn't "read" her clothes because she wasn't wearing any. That is brilliant writing met with fearless acting.
The Mystery of the "I AM SHER-LOCKED" Password
The climax of the episode hinges on a phone password. It’s a moment of vulnerability that Pulver plays with heartbreaking subtlety.
She goes from being the smartest person in the room to someone whose pulse betrayed her. It’s a fast transition. One second. That’s all she had to show the audience that Irene actually cared. If she hadn't sold that moment, the whole episode would have fallen apart.
Where Can You See Lara Pulver Now?
If you’ve finished Sherlock and you’re craving more of that energy, Pulver has a diverse filmography. She’s great in The Alienist: Angel of Darkness. She also showed up in Underworld: Blood Wars, though that’s a very different kind of role.
For those who want to see her range, her theater work is where she truly shines. She has a gravity on stage that is hard to replicate on camera.
Key Takeaways for Fans of The Woman
If you’re looking to dive deeper into the world of Irene Adler and the woman who brought her to life, here is how you should approach it.

First, go back and re-watch "A Scandal in Belgravia" but ignore Sherlock. Watch Irene. Watch how she mirrors his body language. It’s a masterclass in acting.
Second, check out the original story, "A Scandal in Bohemia," by Arthur Conan Doyle. You’ll see just how much Pulver and the writers modernized the character while keeping the core truth: she is the only person to ever outwit the great detective.
Finally, keep an eye on Lara Pulver’s upcoming projects in the West End. While many hope for a Sherlock Series 5, it’s unlikely we’ll see her return to that specific red-soled heel anytime soon.
To truly appreciate her work, you have to look at the nuances.
- The Voice: Notice the lack of contractions in her speech when she’s being formal.
- The Eyes: She rarely blinks when she’s "on the job."
- The Wardrobe: Every outfit was a costume within a costume.
Lara Pulver didn't just play a character; she defined an archetype for a new generation of viewers. She made Irene Adler more than a footnote in Holmes's life. She made her the main event.
To move forward with your appreciation of the series, start by exploring the works of the other actors who have played the role across different eras to see how the "femme fatale" trope has evolved. Then, look into the production notes of Sherlock Series 2 to understand the lighting and costume choices that made "The Woman" so visually striking. This provides a much deeper context than just knowing a name on a cast list.
