Kimba the White Lion: Symphonic Poem (1991)

After a spoken introduction describing the various musical instruments used, the film tells the story of Kimba the White Lion, from his birth, to his escape from a ship intended to take him far from home. The story is told entirely without dialogue, and showcases a symphonic tome poem composed by Isao Tomita, based in incidental music he composed for the original television series "Jangaru taitei" (1965)

Unfortunately the movie Kimba the White Lion: Symphonic Poem is not yet available on HBO Max.
