'Barbie' director Greta Gerwig says she isn't sure about a sequel, but 'wouldn't want to squash anybody else's dreams'

• Greta Gerwig said she's at "totally zero" when it comes to concocting a "Barbie" sequel.
• Although the "Little Women" and "Lady Bird" director didn't rule "Barbie 2" out completely.
• She also joked that Sylvester Stallone should direct the sequel.

It looks like everyone is living in a "Barbie" world after the Greta Gerwig-directed movie raked in over $350 million in its opening weekend against Christopher Nolan's "Oppenheimer."

Critics have also lavished praise on the Warner Bros. movie, as it has a 90% score on Rotten Tomatoes.

So with all the critical and commercial success, it's only natural to wonder whether the studio is already planning "Barbie 2" with the toy company behind Barbie, Mattel.

Mattel CEO Ynon Kreiz previously told Time magazine that the company is keen to make "more 'Barbie' movies."

"We're looking to create movies that become cultural events. If you can excite filmmakers like Greta and Noah to embrace the opportunity and have creative freedom, you can have a real impact," he said.

Unfortunately, Gerwig isn't sure about taking on a sequel.

Greta Gerwig addresses 'Barbie 2'

Speaking to The New York Times in an interview published Tuesday, the "Little Women" and "Lady Bird" director said she used up all her ideas for "Barbie."

"I feel like that at the end of every movie, like I'll never have another idea, and everything I've ever wanted to do, I did," Gerwig explained.

She added: "I wouldn't want to squash anybody else's dream but for me, at this moment, I'm at totally zero."

So don't expect Gerwig to jump back into Barbie's dreamhouse (or Ken's Mojo Dojo Casa House) — at least not right now.

However, speaking to Uproxx about Ken's obsession with Sylvester Stallone in the movie, Gerwig joked that the "Rocky" star could show up in "Barbie 2," or even direct it himself.

She said: "You never know! Or that he's going to direct it. I mean, he's welcome to it. It would be an honor. It would be such an honor."

What Margot Robbie has said about 'Barbie 2'

While Gerwig isn't sold on the idea of returning, star and producer Margot Robbie confirmed to Time that conversations about a sequel have happened, noting: "It could go a million different directions from this point." 

But Robbie also pointed out that "you fall into a bit of a trap if you try and set up a first movie whilst also planning for sequels." 

So it could be quite some time before we get any confirmation on "Barbie 2."

In the meantime, Mattel is also looking to make movies based on its other properties, like a Hot Wheels movie being developed by J.J. Abrams, and Lena Dunham's Polly Pocket movie.
