Greta Gerwig's upcoming Barbie movie has become the most anticipated project of the year -- because, well, duh. Besides an all-star cast and a nostalgia packed premise, the film offers something we're desperately missing in film at the moment: colour. And fun. And... uh, more fun.

For years, little has been known about the project, besides the fact that it will be about Mattel's famous doll. But finally, the first proper trailer has been released — giving us more of an idea about what to expect when the film is released in July.

And we weren't wrong about thefun.

From the release date to the cast, here's everything we know aboutBarbie.

The Barbie trailer.

The first full trailer for Barbie has been released, offering hints about the plot.

In the beginning, Margot Robbie's Barbie greets other Barbies on the beach before she and Ryan Gosling's Ken drive to the real world in their (convertible pink!) car.

There's also lots of in-jokes: Barbie's feet remain the same shape after she takes off her heels, there's a joke poking fun at the dolls lack of... anatomy, and a beef between Kens results in jokes about them all "beating each other off".

Based on cast posters, we also learned that all the Barbies have impressive achievements, from President to Nobel Prize winner, while the Kens are... just Kens.

This trailer comes months after the release of the first teaser in December 2022, which was narrated by Helen Mirren in a parody of Stanley Kubrick's2001: A Space Odyssey.

Who is part of the cast?

Margot Robbie is set to star as 'Barbie' but the role was reportedly once linked to Anne Hathaway and Amy Schumer.

In an interview with the Hollywood Reporter, Schumershared that she left the film after four months, citing conflict issues.

"They definitely didn’t want to do it the way I wanted to do it, the only way I was interested in doing it," she said.

Robbie will be joined by Ryan Gosling, who will star as one of many 'Kens'.

Shang-Chi'sSimu Liu andDoctor Who'sNcuti Gatwa are set to appear as other 'Kens', while some of other Barbies will be played by Issa Rae, Hari Nef, Dua Lipa and Emma Mackay.

Popstar Dua Lipa's inclusion in the cast — as a mermaid Barbie, no less! — was successfully kept under wraps until the full cast announcement on April 4, and led to a minor internet meltdown.

The film will also star 'humans', including Will Ferrell as the CEO of a toy company.
