Astro Boy (2003 TV series): Astro Boy (アストロボーイ・鉄腕アトム , Asutoro Bōi: Tetsuwan Atomu , lit.  "Astro Boy: Mighty Atom") is a remake of the 1960s anime series of the same name created by Osamu Tezuka, which was produced by his company, Tezuka Productions, Sony Pictures Entertainment Japan, Dentsu, and Fuji Television network.  It was also shown on Animax, who have broadcast the series across its respective networks worldwide, including Japan, Southeast Asia, South Asia, East Asia, and other regions.  It was created to celebrate the birth date of Atom/Astro Boy (as well as the 40th anniversary of the original TV series).  Under the original English name (instead of "Mighty Atom"), it kept the same classic art style as the original manga and anime, but was revisioned and modernized with more lush, high-quality, near-theatrical animation and visuals.  It combined the playfulness of the early anime with the darker, more serious and dramatic Science fiction themes of the manga and the 1980 series.  The anime broadcast in Japan on the same date as Atom's/Astro's birth in the manga (April 6, 2003) across Animax and Fuji Television.  It was directed by Kazuya Konaka and written by Chiaki J. Konaka at the beginning of the series.  Other writers included were Keiichi Hasegawa, Sadayuki Murai, Ai Ohta, Hirotoshi Kobayashi, Kenji Konuta, and Marc Handler, who was also executive story editor.
