During an interview with Vogue in May, Margot explained that the movie aimed to cater to both fans of the Mattel dolls, but also those that don’t like or even ‘hate’ the dolls.

‘We of course would want to honor the 60-year legacy that this brand has,’ she explained to the outlet. ‘But we have to acknowledge that there are a lot of people who aren’t fans of Barbie.’

‘And in fact, aren’t just indifferent to Barbie. They actively hate Barbie. And have a real issue with Barbie. We need to find a way to acknowledge that,’ the star added.
