See Millie Bobby Brown Rock a Fiery Hair Transformation for New Movie

'Damsel' is headed to screens later this fall.

Millie Bobby Brown has joined the ever-growing lineup of celebs debuting a new hairstyle in the first few weeks of 2023.

But unlike Idina Menzel, Hilarie Burton, and Salma Hayek's new 'dos, we can confirm Brown's most recent haircut was a decision made in preparation for her new movie.

The Stranger Things actress will star in Netflix's upcoming film, Damsel, which is set to be released to the streamer later this year (on Oct. 13, to be exact). As sets begin to be staged and cameras get ready to roll, Brown has completely transformed her look for the new character.

Netflix debuted the 18-year-old's chic, short red bob in a now-deleted Instagram Story featuring a photo of the star in character posing with a sword, and encouraged fans to "save the date" for her upcoming release, per screenshots shared by Cosmopolitan.

The streaming giant also teased Brown's new hairstyle in an Instagram video highlighting clips from all of the latest films coming to the platform in 2023, "NEW YEAR, NEW MOVIES! SAVE THE DATES 🗓️," the caption read.
