The Beatles Yellow Submarine.

Yellow Submarine is a 1968 British animated musical fantasy comedy film inspired by the music of the Beatles, directed by animation producer George Dunning, and produced by United Artists and King Features Syndicate. Initial press reports stated that the Beatles themselves would provide their own character voices; however, aside from composing and performing the songs, the real Beatles participated only in the closing scene of the film, while their cartoon counterparts were voiced by other actors. The film received widespread acclaim from critics and audiences alike, in contrast to some of the Beatles' previous film ventures. It has also been credited with bringing more interest in animation as a serious art form. Time commented that it "turned into a smash hit, delighting adolescents and aesthetes alike".
