Just as Marvel had gone from ailing comic-book publisher to Hollywood behemoth, the toymaker could leverage its intellectual property at the multiplex. Kreiz told me, “My thesis was that we needed to transition from being a toy-manufacturing company, making items, to an I.P. company, managing franchises.”

She told me, “There are people who adore Barbie, people who hate Barbie—but the bottom line is everyone knows Barbie.” She wanted a film adaptation to confront those “sharp edges, ” but when she met with Kreiz she led with her desire to take the brand seriously.

Kreiz, meanwhile, hired a veteran of Miramax, Robbie Brenner, to head up the newly minted Mattel Films. Her first task: assemble a team of development executives to rummage through Mattel’s toy chest and identify I.P. that could be fodder for Hollywood studios. Mattel would help match properties with writers, actors, and directors; studios would provide all the funding. The brands, and audiences’ familiarity with them, were their own form of currency. Brenner told me, “In the world we’re living in, I.P. is king. Pre-awareness is so important.”

Jeremy Barber, an agent at U.T.A. who represents Gerwig and Baumbach, is close with Brenner, so he could be blunt. “Are you crazy?” he told her. “You should’ve come into this office and thanked me when Greta and Noah showed up to write a fucking Barbie movie!”

Barber told me that Mattel had figured out how to “engage with filmmakers in a friendly way.” Gerwig, meanwhile, was looking to move beyond the small-scale dramas she was known for. “Greta and I have been very consciously constructing a career,” Barber explained. “Her ambition is to be not the biggest woman director but a big studio director. And Barbie was a piece of I.P. that was resonant to her.”

Although Barber was pleased with the “Barbie” partnership, he was clear-eyed about its implications. “Is it a great thing that our great creative actors and filmmakers live in a world where you can only take giant swings around consumer content and mass-produced products?” he said. “I don’t know. But it is the business. So, if that’s what people will consume, then let’s make it more interesting, more complicated.”

The future of moviegoing now seems increasingly tenuous, and studios have leaned on pre-awareness as a means of drawing people to theatres: a nostalgia play like “Hot Wheels” is seen as a safer bet than an original concept. The box office has borne this out: the ten highest-grossing films of 2022 were all reboots or sequels. Disney’s much derided strategy of remaking “Aladdin” and other animated classics as live-action spectacles has largely paid off; by contrast, Pixar’s recent attempt at an original story, “Elemental,” bombed.

The mandate for audience recognition has pushed artists to take increasingly desperate measures—including scrounging up plotlines from popular snacks. Eva Longoria recently directed the Cheetos dramedy “Flamin’ Hot”; Jerry Seinfeld is at work on “Unfrosted: The Pop-Tart Story.”

creating “a story where there hadn’t been a story” felt like solving “an intellectual Rubik’s Cube.”

Whereas Scott’s “Monopoly” was shamed into nonexistence, advance screenings of “Barbie,” billed as “blowout parties,” are selling out. Nevertheless, the film’s slogan—“If you love Barbie, this movie is for you. If you hate Barbie, this movie is for you”—is indicative of the tightrope it has to walk. “Barbie” is somehow simultaneously a critique of corporate feminism, a love letter to a doll that has been a lightning rod for more than half a century, and a sendup of the company that actively participated in the adaptation.

When Robbie’s character ventures beyond Barbie Land, Gerwig explained, the film’s visual language also changes: “The way the camera moves and the way it feels is different once we’re in the real world.”

Mattel was sometimes uneasy with Gerwig’s interest in the brand’s missteps. In 1964, the company released a doll named Allan, whose packaging marketed him as “Ken’s buddy,” with the tagline “All of Ken’s clothes fit him!” Allan was soon pulled from shelves. When Gerwig learned about him, she found the ad copy both sad and amusing. In “Barbie,” Allan is played by Michael Cera, and much is made of the fact that his relationship to Ken is his main identifying feature. The company, Gerwig remembered, required some convincing: “There was just an e-mail that went around where they said, ‘Do you have to remind people that this was on the box?’ ”

Gerwig told me, “Barbie seems so monolithic, and there’s a quality where it just seems as if she was inevitable, and she’s always existed. I think all the dead ends are a reminder that they were just trying stuff out.” Although she understood why Mattel wanted “to protect Barbie,” she felt that “dealing with all the strangeness of it is a way of honoring it.”

A rival, Kenner, was having runaway success with “Star Wars” action figures, and Mattel scrambled to launch a science-fantasy saga of its own. Play-testing had revealed that young boys fixated on the notion of “power,” and that a muscle-bound hero was more appealing than the slighter action figures of the era. This intelligence yielded He-Man and the Masters of the Universe. When a retailer pointed out that kids would have no idea who these characters were—even then, pre-awareness was a consideration—Mattel hastily produced comic books that explained their backstories.

Brenner sat at the head of a long table while her right hand, Kevin McKeon, provided updates on various projects. His descriptions sometimes sounded like a Hollywood version of Mad Libs. A screenwriter, he informed the group, was at work on an American Girl script that would be “ ‘Booksmart’ meets ‘Bill & Ted.’ ” Jimmy Warden, the screenwriter of “Cocaine Bear,” had devised a horror-comedy about the Magic 8 Ball.

McKeon seemed most excited by Kaluuya’s Barney project, which would be “surrealistic”; he compared the concept to the work of Charlie Kaufman and Spike Jonze. “We’re leaning into the millennial angst of the property rather than fine-tuning this for kids,” he said. “It’s really a play for adults. Not that it’s R-rated, but it’ll focus on some of the trials and tribulations of being thirtysomething, growing up with Barney—just the level of disenchantment within the generation.” He told me later that he’d sold it to prospective partners as an “A24-type” film: “It would be so daring of us, and really underscore that we’re here to make art.”

Talk turned to a few recent pitches that had surprised the team. “Somebody just asked me about Bass Fishin’, which is, like, a toy fishing rod,” Bassin said. The pitch was for an “intense sports drama about this cheating scandal in competitive fishing”—an attempt, it seemed to me, to Trojan-horse a story that the writer actually wanted to tell into a conceit that might be green-lighted.

Gerwig’s “Barbie,” for all its gentle mockery of Mattel, has already paid dividends for the company. A fifty-dollar doll resembling Robbie as she appears in the film, unveiled in June, has sold out; so has a seventy-five-dollar model of Stereotypical Barbie’s pink Corvette.

If you are wondering whether Barbie is a satire of a toy company’s capitalist ambitions, a searing indictment of the current fraught state of gender relations, a heartwarming if occasionally clichéd tribute to girl power, or a musical spectacle filled with earworms from Nicki Minaj and Dua Lipa, the answer is yes. All of the above. And then some.

Gerwig still can’t seem to believe she got away with making this version. “This movie is a goddamn miracle,” she says. She calls it a “surprising spicy margarita.” By the time you realize the salted rim has cayenne mixed in, it’s too late. “You can already taste the sweetness and you sort of go with the spice.”

Every single actor I spoke to cited Gerwig and the sharp script as the reason they joined the film. “I knew this was not going to shy away from the parts of Barbie that are more interesting but potentially a little bit more fraught,” says Hari Nef, who plays a doctor Barbie. “The contemporary history of feminism and body positivity—there are questions of how Barbie can fit into all of that.”

At one point Richard Dickson, COO and president of Mattel, says he took a flight to the London set to argue with Gerwig and Robbie over a particular scene, which he felt was off-brand. Dickson dials up his natural boyish exuberance, imitating himself righteously marching off the plane to meet them. But Gerwig and Robbie performed the scene for him and changed his mind. “When you look on the page, the nuance isn’t there, the delivery isn’t there,” explains Robbie.

Robbie had laid the groundwork for this with Mattel’s CEO when she met with him in 2018 in the hopes that LuckyChap could take on the Barbie project. “In that very first meeting, we impressed upon Ynon we are going to honor the legacy of your brand, but if we don’t acknowledge certain things—if we don’t say it, someone else is going to say it,” she says. “So you might as well be a part of that conversation.”

“The most important transition was from being a toy-manufacturing company that was making items to becoming an IP company that is managing franchises,” he says. It’s a particularly prescient strategy at a moment when superhero fatigue has set in and studios are desperate to find new intellectual property with a built-in fan base—from Super Mario Bros. to Dungeons & Dragons.

Issa Rae, 38, who plays President Barbie, argues that the entire point of the film is to portray a world in which there isn’t a singular ideal. “My worry was that it was going to feel too white feminist-y, but I think that it’s self-aware,” she says. “Barbie Land is perfect, right? It represents perfection. So if perfection is just a bunch of white Barbies, I don’t know that anybody can get on board with that.”

Still, in an interview for this story, Brenner called Gerwig’s film “not a feminist movie,” a sentiment echoed by other Mattel executives I spoke with. It was a striking contrast to my interpretation of the film and conversations with many of the actors, who used that term unprompted to describe the script. When I relay Mattel’s words to Robbie, she raises an eyebrow. “Who said that?” she asks then sighs. “It’s not that it is or it isn’t. It’s a movie. It’s a movie that’s got so much in it.” The bigger point, Robbie impresses upon me, is “we’re in on the joke. This isn’t a Barbie puff piece.”

Gerwig’s team built an entire neighborhood made up of Dream Houses that were missing walls. The actors had to be secured by wires so they wouldn’t topple off the second floors. The skies and clouds in the background were hand-painted to render a playroom-like quality, as was much of the rest of the set.

But McKinnon, 39, watched her sister and friends play with the dolls: they cut Barbie’s hair, drew on her face, and even set her on fire. She theorizes, “They were externalizing how they felt, and they felt different.” So when Gerwig offered McKinnon the role of Weird Barbie, a doll that’s been played with a little too aggressively in the real world, she jumped at the chance. McKinnon was impressed by the way the script dealt with girls’ complicated attachments to the doll. “It comments honestly about the positive and negative feelings,” she says. “It’s an incisive cultural critique.”

“We’re looking to create movies that become cultural events,” Kreiz says, and to do that Mattel needs visionaries to produce something more intriguing than a toy ad. “If you can excite filmmakers like Greta and Noah to embrace the opportunity and have creative freedom, you can have a real impact.”
