Netflix upcoming Alice in Wonderland and The Wizard of Oz crossover, Dorothy & Alice, has found its screenwriter.

Collider reports the streaming service has hired Anna Klassen to pen the script for the upcoming movie. Klassen rose to prominence after her spec script, When Lightning Strikes, was voted to the 2017 Black List. The script was about a young J.K. Rowling on the verge of writing Harry Potter. Klassen will also work on a second currently unrevealed project with the streaming service.

Klassen confirmed the news on Twitter. "The Cheshire Cat is out of the bag," she wrote. "I’m writing DOROTHY & ALICE for @Netflix, a fantasy adventure epic. I grew up reading these books & this project has been endlessly fun to craft - to reinvent treasured characters and explore the worlds I wanted to inhabit as a kid."

Dorothy & Alice was first written by Justin Merz, a school teacher in Santa Monica. The story is billed as a crossover between the two classic fantasy heroines. Years after she visited the mystical land of Oz, Dorothy begins suffering from visions of the mystical realm in being destroyed. Sent to a mental hospital, she meets Alice and works with her to try and save the worlds they visited in their youth.
