Paul is reportedly planning an animated film based on his children's book "High in the Clouds," featuring his character Wirral the Squirrel.
The original picture-book was co-written by McCartney and Philip Ardagh, author of the Eddie Dickens series. Illustrations – of Wirral, his friend Froggo, and their quest to find the island of Animalia – were provided by Geoff Dunbar. McCartney has been promising a movie version of the book for years, but this is the first evidence of Wirral the Squirrel becoming a big-screen star.
The trick, it seems, was McCartney's soundtrack. "Paul said he would commit to a score of original songs as part of it," Lynne told Variety this week. "Bob and I had never focused on animation in our career, but that got our attention."
