Since her breakout role in Netflix’s Stranger Things, Millie Bobbie Brown has become something of a phenomenon. Just last year, she became the youngest ever entry on TIME’S Most Influential list. And it was recently announced that  she will star alongside Helena Bonham Carter and Henry Cavill in the new Sherlock Holmes film. 

In more exciting Brown-related news, she’s currently developing a new Netflix film with her sister, Paige. 

A Time Lost will be based on an original story penned by the two sisters. According to Hollywood Reporter, it follows a long-standing feud between two families that comes to a head when one of their teenage daughters is diagnosed with cancer.

“We are so grateful to Netflix for their confidence in us and this beautiful story, which we have spent years writing and developing,” the Brown sisters said on Tuesday (10 September) in a statement. “It’s about friendship, family and overcoming obstacles when it feels like the world is pushing you down. It’s been a labour of love, literally.”

Netflix’s Lisa Nishimura applauded Brown for being “extraordinary”, adding: “Millie is an extraordinary creative talent. We’ve been lucky to have her in our family from the beginning of her career. It is a genuine thrill to witness Millie bring her distinct vision to the screen, now as a writer and producer, alongside her sister on this wonderful film.”

Although it is unknown who will star in the film, up-and-coming screenwriter Anna Klassen has been confirmed as part of the film’s production. We’ll need to wait a little while longer to get any further details and a release date.

While we wait, the big question that fans are asking right now is: will there be a Stranger Things series 4? 

Director Ross Duffer confirmed to Vulture that there will be a season four, and hinted that it would be the last one. “We’re thinking it will be a four-season thing and then out,” he said. “We just have to keep adjusting the story… Though I don’t know if we can justify something bad happening to them once a year.” 

But in an interview with Entertainment Weekly, executive producer Shawn Levy suggested that the series won’t stop there.

“Hearts were heard breaking in Netflix headquarters when the brothers made four seasons sound like an official end, and I was suddenly getting phone calls from our actors’ agents,” he said. “The truth is we’re definitely going four seasons and there’s very much the possibility of a fifth. Beyond that, it becomes I think very unlikely.”

Whatever happens, it looks like Brown has a busy couple of years ahead of her. And we can’t wait to see what she delivers us.
