Viewers are bursting into tears after discovering the subtle backstory of the ending to the Barbie movie

Greta Gerwig has opened up about the meaning behind the beautiful ending sequence of the Barbie movie.

For those of you who haven't seen the director's incredible movie, firstly, what are you doing with your life secondly, there will be spoilers, so turn away now.

Towards the end of the film, when Barbie decides to become human, there is a montage of home videos showing families, women and young girls from different walks of life.

Now, if the scene didn’t bring you to tears, the story behind that scene just might leave you as a blubbering mess.

“I had this idea that I wanted that moment in the film to be truly made by the people who made the movie,” Gerwig said in an interview with Andrew Freund.

The director then explained how she asked the crew, cast and editorial team members to submit their own videos for her to use in that scene.

“We got the most beautiful moments from people's lives. It was people’s friends, aunts, mothers, daughters, sisters like it was just extraordinary.”

Gerwig’s team received hundreds of videos, which they then used to put together that tear-jerking montage scene.

“With something like Barbie, that’s such a behemoth of an international brand and icon and it can be something that feels so kind of impersonal,” said Gerwig.

“It was a way to be like ‘this has only ever been made by human beings’.”

She added: “Movies, dolls. Human beings make them. They’re not handed down from on high, they are just made.”

This intricate detail has moved fans of the film bringing many to tears.

One viewer said: “I can’t stop thinking about the montage of real women scene in Barbie. I’m tearing up just thinking about it.”

Another wrote it was 'a piece of media that has altered my brain chemistry. It was peak girlhood, womanhood, motherhood, everything'.

A third wrote: “When a movie makes a point about being a human with feelings and thoughts and dreams and desires,” said another, “It always gets me. And that’s exactly what the ending of Barbie was.”

It's clear that the fans have been loving the film with Barbie racking up $155 million at the domestic box office in addition to another $182 million internationally.

“Every film I make has to come from a personal place,” said Gerwig. “These are just people making this.”
