Amazon MGM Studios is developing a live-action film adaptation of ND Stevenson’s 2025 fantasy novel “Scarlet Morning,” with “Loki” director Kate Herron attached to direct, according to The Hollywood Reporter. Herron will also produce through her new banner, A Bag of Rats, and co-write the script with Kari Granlund.
Roy Lee is producing through Vertigo Entertainment. Darlene Caamaño Loquet is producing via her company Oh My Darlin’ Entertainment, and Aubrey Davis is producing for A Bag of Rats. Granlund and Jakob Pollack are set as executive producers.
The Scarlet Morning Film Adaptation Details
“Scarlet Morning” is a middle-grade illustrated fantasy novel published in September 2025 by HarperCollins imprint Quill Tree Books. The story follows two orphans who grow tired of waiting for their parents to come home and instead join a pirate crew on a mission to save the world of Dickerson’s Sea, according to The Hollywood Reporter.
The project is a notable early step for two production companies. It marks the first project for Herron’s A Bag of Rats banner, and it’s the first feature for Caamaño Loquet’s Oh My Darlin’ Entertainment.
What It Means For Fans Of ND Stevenson
The “Scarlet Morning” movie gives Stevenson a shot at live-action success following the animated hit “Nimona.” That 2015 graphic novel was a National Book Award finalist and later became a Netflix movie that landed an Oscar nomination for best animated feature.
Stevenson’s other credits include serving as creator and showrunner on the “She-Ra and the Princesses of Power” reboot at DreamWorks Animation Television, along with co-creating the best-selling Boom! Studios comic series “Lumberjanes.” For readers who followed the author through those projects, “Scarlet Morning” extends that track record into a new middle-grade property built around pirates and a search for lost family.
Background On The Filmmakers
Herron’s recent credits include directing episodes of the Emmy-nominated Apple TV series “Margo’s Got Money Troubles” and the fourth episode of the second season of HBO’s “The Last of Us.” She is also attached to direct a feature adaptation of “The Sims,” which is set up at Amazon MGM, and she directed the first season of “Loki” for Disney+.
Lee previously worked with Caamaño Loquet on “Nimona,” and Caamaño Loquet served as senior vice president at Nickelodeon Movies before launching Oh My Darlin’ Entertainment. Davis, now producing for A Bag of Rats, previously developed and produced projects including “The Afterparty” for Apple TV while at Phil Lord and Chris Miller’s Lord Miller Productions, according to the outlet.
What’s Next For Scarlet Morning
No casting has been announced for “Scarlet Morning,” and Amazon MGM hasn’t released a filming timeline or release date for the project. The studio’s pairing of Lee and Caamaño Loquet reunites two key players from the “Nimona” film, giving the new project a built-in creative link to one of Stevenson’s biggest successes to date.
