Greta Gerwig admitted that she was "terrified" to direct and co-write the upcoming Warner Bros. "Barbie" film starring Margot Robbie and Ryan Gosling.

The 39-year-old filmmaker told Dua Lipa that she was excited but also worried about taking on the first ever live-action movie based on the iconic Mattel Doll.

"It was terrifying," the three-time Academy Award nominee said during a Friday appearance on the 27-year-old British singer's podcast "At Your Service."

Gerwig continued, "I think there’s something about starting from that place where it’s like, ‘Well, anything is possible.'"

She added, "It felt like vertigo starting to write it. Like, where do you even begin? What would be the story?"

"I think it was that feeling I had knowing that it would be really interesting terror. That's usually where the best stuff is."

"When you’re like, ‘I am terrified of that,'" the "White Noise" star said. "Anything where you’re like, ‘This could be a career-ender,’ then you’re like, ‘OK, I probably should do it.'"

Gerwig enlisted her partner and frequent collaborator Noah Baumbach to co-write the screenplay in 2019. In 2021, she signed on to direct the romantic comedy.

Production on "Barbie" began last March and the film is set to be released on July 21, 2023.
