Elle Fanning and Julianne Moore will star in Moonsong: A Life in Seven Verses, a new film from Rebecca Miller (Maggie's Plan, She Came to Me). Deadline reported that the film, based on the book Margaret Wise Brown: Awakened by the Moon by Leonard S. Marcus, tells the story of the beloved children's book author whose classic books include Goodnight Moon and The Runaway Bunny, originally published in the 1940s.
Miller is writing the script and will direct the project, which was brought to her and her Round Films producing partner Damon Cardasis by Amanda Goodwin, Keri Selig, and Sasha Alexander. Martin Scorsese will executive produce, with production to begin in spring 2027.
