Regarded by many as the "God of Manga," Osamu Tezuka was a prolific author and artist, and is generally regarded as the single figure responsible for developing Japan's massive manga and anime industries. His cinematic art style and novelistic narratives have made his work as universally accessible and relevant now as when first published in Japan. A list of his well-known and universally loved work includes the classic Jungle Emperor Leo (also known as Kimba the White Lion), Black Jack, Adolf, Mighty Atom (known as Astro Boy in the U.S.) and Metropolis (made into a hit anime film in 2001).
