Yellow Submarine (1968)

The acclaimed animated fantasy based on a plethora of mid-career Beatles songs, sees the Fab Four battle the Blue Meanies for the sake of Sgt. Pepper, the Nowhere Man, Strawberry Fields, and Pepperland. The first full-length British animated feature in 14 years features a host of talented cartoonists. Fascinating LSD-esque animation and imagery. Speaking voices provided by John Clive (John), Geoff Hughes (Paul), Peter Batten (George), and Paul Angelis (Ringo). The Beatles themselves do appear in a short scene at the end of the film. Martin fills in as music director, and Segal of Love Story fame co-scripts.
