Honestly, walking into the theater for Greta Gerwig’s Barbie, nobody quite expected the absolute chaotic brilliance of the ensemble. It wasn't just a movie. It was a cultural earthquake. But the real magic? It lived in the cast of Barbie film, a group of actors who took plastic-perfect characters and made them feel deeply, awkwardly human.
You’ve got the obvious heavy hitters, sure. Margot Robbie and Ryan Gosling are basically the sun and the moon of this universe. But when you look closer, the supporting cast is a bizarre, beautiful mix of Oscar winners, British sitcom stars, and actual pop royalty. It's the kind of casting that makes you wonder how they ever got everyone in the same room.
The Faces of Barbieland: It’s Not Just One Barbie
Most people think of "Barbie" as a single person. In this movie, it’s a title. A status. A literal workforce.
Margot Robbie is our "Stereotypical Barbie." She’s the one with the blonde hair and the existential dread. It’s hard to imagine anyone else in the role now, but did you know she wasn't the first choice? Amy Schumer was originally attached to a version of this project years ago. Later, Anne Hathaway was in the mix. But Robbie didn't just act; she produced. She's the reason the movie has that specific, self-aware edge.
Then you have the "other" Barbies. They aren't just background fluff. They run the world.
- Issa Rae as President Barbie. She’s got the sash, the smile, and the total authority.
- Emma Mackey as Physicist Barbie. Fun fact: fans have pointed out for years how much Mackey and Robbie look alike. Gerwig actually leaned into this, though she eventually realized they don't look that similar once they were in the same costumes.
- Hari Nef as Doctor Barbie. Her performance was a standout, bringing a dry, almost "Jennifer Coolidge-style" wit to the medical professional of the group.
- Alexandra Shipp as Writer Barbie, and Sharon Rooney as Lawyer Barbie.
And then there's Kate McKinnon. Weird Barbie. We’ve all had one. The doll with the chopped hair, the marker stains on the face, and the legs permanently stuck in the splits because someone played with her "too hard." McKinnon is basically the Yoda of Barbieland, and she plays it with a frantic, hilarious energy that only a Saturday Night Live alum could pull off.

The Kens: More Than Just Beach
If Barbie is everything, Ken is... just Ken. But the cast of Barbie film wouldn't be half as iconic without the "Kenergy" brought by the men.
Ryan Gosling is the standout. People actually doubted him at first. Too old? Too serious? Then he dropped "I'm Just Ken," and the internet imploded. Gosling played the role with a mix of fragile masculinity and pure, unadulterated commitment. He reportedly took the job after seeing his daughter's Ken doll lying face down in the dirt next to a squashed lemon. He felt Ken’s story had to be told.
But he’s not the only Ken in the Mojo Dojo Casa House.
- Simu Liu plays the "Rival Ken." He’s the one constantly challenging Gosling to a "beach-off." Liu’s background in dance and stunts made those synchronized Ken battles look way better than they had any right to.
- Kingsley Ben-Adir is the Ken who is just happy to be there.
- Ncuti Gatwa and Scott Evans (yes, Chris Evans’ brother) round out the main Ken squad. Gatwa, known for Sex Education and Doctor Who, brings a massive amount of charisma to a character that literally has no purpose other than to exist near a Barbie.
And then there is Michael Cera. He plays Allan. There’s only one Allan. He’s the guy who fits into all of Ken’s clothes but somehow doesn't fit into the Ken hierarchy at all. Cera’s awkward, "I don't want to be part of this" vibe is the perfect foil to the hyper-masculine Ken takeover.
The Real World: The Human Element
When Barbie leaves her pink paradise, she hits the real world, and that’s where the emotional weight of the film kicks in.

America Ferrera plays Gloria, a Mattel employee who is struggling with the pressures of being a woman in the real world. Her monologue? It’s legendary. It’s the heart of the movie. Ferrera has talked about how they did dozens of takes of that speech, and every time, the cast and crew were in tears.
Her daughter, Sasha, is played by Ariana Greenblatt. She starts as the cynical teen who calls Barbie a "fascist" and ends up being the one who helps save Barbieland.
And let’s talk about the Mattel boardroom. Will Ferrell plays the CEO. It’s a classic Ferrell performance—loud, slightly incompetent, and weirdly obsessed with the "spark" of imagination. He’s joined by Jamie Demetriou and Connor Swindells, who play the bumbling executives trying to put Barbie back in her box.
The Cameos You Might Have Missed
The cast of Barbie film is peppered with "blink-and-you'll-miss-it" appearances.
- John Cena as Merman Ken. This happened because Cena was filming Fast X right next door and bumped into Margot Robbie.
- Dua Lipa as Mermaid Barbie. She also did the lead single for the soundtrack, "Dance the Night."
- Rhea Perlman as Ruth Handler. She plays the creator of Barbie, appearing as a ghostly, wise grandmother figure in the halls of Mattel.
- Helen Mirren as the Narrator. You never see her, but her voice is the glue that holds the meta-humor together.
- Ann Roth as the old lady on the bench. She isn't a famous actress—she’s actually an Oscar-winning costume designer. Gerwig insisted on keeping that scene because it represented the beauty of aging, something Barbie had never experienced.
Why This Cast Worked So Well
It wasn't just about big names. It was about vibe. Greta Gerwig and casting director Allison Jones looked for "Barbie energy." This meant being able to play something totally ridiculous with 100% sincerity.

If Ryan Gosling had winked at the camera once, the whole thing would have fallen apart. Instead, he treated Ken’s struggle for a "brewski beer" as seriously as a Shakespearean tragedy. That’s the secret sauce.
The diversity of the cast was also a huge talking point. You have different body types, ethnicities, and backgrounds. It felt like a modern reflection of what the Barbie brand is trying to be now, rather than the narrow definition of beauty it was stuck in for decades.
How to Dive Deeper into the Barbie World
