No stranger to the animation world, Paul McCartney has dabbled in various animated projects throughout his career, most notably the full-length feature Yellow Submarine in 1969. Now, according to a report by Toon Barn , the former Beatle has made a deal with HBO to develop an animated feature that showcases some of the songs from his solo career such as “Mary Had a Little Lamb” and “Silly Love Songs.”
McCartney is also reportedly working with Bob Shaye and Michael Lynn of New Line and Unique Films for another animated feature based on his 2005 children’s book “High in the Clouds.” The book focuses on a courageous squirrel named Wirral who joins forces with a frog named Froggo in order to save his woodland home from the polluted Megatropolis.
Back in the eighties, McCartney also purchased the movie rights to the popular British comic strip "Rupert Bear" in hopes of making a full-length animated feature. While the project didn’t materialize, he was still able to deliver an animated short called Rupert and the Frog Song.
