The Maison de Cheveux hair salon in the Big Easy posted on Instagram a photo of the Twilight actress' new hue, bright orange with dark roots.
"Kristen Stewart gettin her hair ready for a new role! #americamultra #awesomecolor#houseofhair," the salon wrote on the caption for the photo.
Shooting is scheduled to begin this month for American Ultra, starring Stewart opposite Jesse Eisenberg. Stewart is the girlfriend of an unmotivated stoner played by Eisenberg, who becomes a target of a government operation.
Uma Thurman also stars in the action-comedy.
"Simply put, American Ultra will be the most fun you can possibly have in a movie theater without the use of drugs, fireworks or canola oil," producer Mike Bregman said of the film.
