Blue meanies make war on the peaceful music lovers of Pepperland, one of whom travels to another dimension—an expressionist 1960s Liverpool—to enlist John, Paul, George, and Ringo, who intimidate the meanies by impersonating a legendary band. This 1968 Beatles musical gets somewhat plot heavy near the end, but it’s a marvel of innocence and free association, blending several animation techniques in a loose narrative full of gentle bad puns and flowing visual segues. Except for “Lucy in the Sky With Diamonds,” whose dense lyrics are sparingly evoked in gorgeous watercolors, the visual imagery is at least as complex as the song lyrics and uses light metaphor more than literal illustration or heavy symbolism. Directed by George Dunning. The 1999 rerelease includes footage featuring the song “Hey Bulldog,” which was omitted from the original.
