McCartney is producing and contributing songs to the film, which centers on an imaginative teenage squirrel named Wirral who find himself pulled into a ramshackle gang of teenage rebels who live high in the clouds. He accidentally antagonizes Gretsch the owl, the tyrannical leader who steals the voice of anyone who upstages her.
Timothy Reckart is directing from a script by Jon Croker, who has credits on the Paddington movies and “Fantastic Beasts: The Crimes of Grindelwald. Besides McCartney, the producers include Bob Shaye (“The Lord of the Rings” trilogy), the late Michael Lynne, Sidonie Dumas, Christophe Riandee, Nicolas Atlan and Terry Kalagian (Gaumont).
“High in the Clouds” was published in 2005. McCartney set the project up with Shaye and Lynne
