Can Barbie be the new Iron Man in a Mattel universe?

It may sound like an unlikely comparison, but the boss of toy company Mattel would like Barbie to be the next Iron Man.
That's because Ynon Kreiz aspires to create a "Mattel universe", he tells me - emulating the success of the Marvel universe, which has spawned dozens of hit films for Disney from a cast of comic-book characters like Thor, Captain America and Guardians of the Galaxy.
This is the strategy behind the Barbie movie, which comes out on 21 July. Kreiz began working on it when he became CEO of Mattel in 2018 and he remains executive producer.
Barbie and Ken are played by Margot Robbie and Ryan Gosling, with Greta Gerwig directing.
Kreiz acknowledges there is some risk in giving Barbie the Hollywood treatment, working with directors and writers who have their own creative ideas.
It's clear even from the trailer that Barbie is the butt of jokes.
If you're being generous, she is portrayed as naïve and innocent. If you aren't, she's shallow and superficial, obsessed with appearance and unable to comprehend the meaning of sex, death - or life without high heels.
Barbie's "Dreamland" is a pink utopia, divorced from reality.
"This movie has been 64 years in the making (Barbie launched in 1959)," says Kreiz, "but it represents how the culture sees Barbie today."
Barbie remains Mattel's biggest-selling brand, making the company more than £1bn ($1.5bn) annually. Its other brands include Hot Wheels, Masters of the Universe, Monster High, Bob the Builder and Thomas the Tank Engine.
Kreiz argues Mattel's other brands also have the potential to be turned into successful spin-offs.
"The devil works hard but Barbie's marketing team is working harder," according to marketing expert Mike Buonaiuto, author of Founder Therapy, who admires the inventive advertising the team behind the film has been up to, including the Airbnb listing of a Barbie Dreamhouse.
"But let's be honest," Buonaiuto points out, "the opportunity for the Mattel universe is vastly different to Marvel's, and whilst Barbie is being powered by millennial nostalgia collaborations, try and do the same for Thomas the Tank Engine or Hot Wheels and you probably won't get the same result.
"The depth of world-building Mattel can pull from isn't competition for Marvel's."
But the recent collapse of Toys R Us shows why toymakers like Mattel need to diversify beyond the sale of physical products, adds Buonaiuto.
Barbie advert
Barbie was first introduced in America in 1959, developed by Ruth Handler, co-founder of Mattel.
Before Barbie, dolls typically took the form of babies, so children could play at being a nurturing parent. However, Barbies encouraged children to play at being adolescents, imagining their future selves through the dolls.
As the original TV adverts that ran during Mickey Mouse Club told children: "Someday I'm going to be exactly like you."
This proved alluring and good business. More than a billion Barbie dolls had been sold by the early 1990s.
But there have also been questions about what exactly Barbie dolls teach children, especially around body image.
The original Barbie design was extremely skinny and the messaging reinforced unhealthy ideas. One infamous slumber party set created in the mid-1960s featured bathroom scales fixed at 110 pounds (50kg) and a dieting book that advised: "Don't eat".
Another talking Barbie created in the early 1990s had the doll saying, "Math class is tough." Mattel later apologised.
These issues continued to affect people's perception of the brand and arguably lay behind a dip in popularity around a decade ago.
Mattel has learned lessons and is now keeping up with the times, says Kreiz.
"Barbie is a flag carrier for diversity and inclusivity," he says, "with more than 170 different Barbie types in terms of body shape and skin colour, and Barbie has more than 200 careers, so girls can explore their potential in different ways."
Barbie has recently brought out dolls with disabilities, prosthetic limbs, and one with Down's Syndrome.
