TheBarbiefilm has an iconic cast, through and through.

But while everyone’s familiar with the big names of the cast, there’s one name that some moviegoers might not have been familiar with — and they may not even be familiar with her face. They’ll definitely know her work though.

That person is Oscar-winning costume designerAnn Roth.

Roth is featured in the first trailer forBarbieand shares the cutest (and also funniest) scene with starMargot Robbie. While Robbie is having a bit of a tough moment, she encounters Roth on a bench, looks at her and tells her she’s beautiful. Without batting an eye, Roth tells her that she knows, and the two of them laugh.

In an interview withRolling Stoneearlier this month, director and co-writerGreta Gerwigdiscussed Roth’s cameo in her film.

“I love that scene so much,” said Gerwig, adding that Roth is a “legend.”

Further breaking down the scene, Gerwig continued: “It’s a cul-de-sac of a moment, in a way — it doesn’t lead anywhere. And in early cuts, looking at the movie, it was suggested, ‘Well, you could cut it. And actually, the story would move on just the same.’ And I said, ‘If I cut the scene, I don’t know what this movie is about.’”

The tug-at-your-heart-strings bit, to Gerwig, is “the heart of the movie. The way Margot plays that moment is so gentle and so unforced.”

Roth, 91, has more than 100 credits to her name and has been nominated for five academy awards for her costume work. She’s won two — forThe English PatientandMa Rainey’s Black Bottom.

Whether she was quite literally stealing the carpet dressed up as the ‘60s Solo in the Spotlight figurine or channeling the 1992 Totally Hair Barbie in disco glam, the actress was all for bringing the Mattel icon to life even further.

“We’re finding Barbie references from decades past and justdoing it really for the big Barbie fansout there, people who are actually collecting those Barbies. We’re hoping to get them excited,” Robbie told PEOPLE exclusively at theBarbieworld premiere.
