Astro Boy Theme Song Lyrics
Behind the Music: Meaning & Story
The Astro Boy theme song for the 2009 film is a sweeping orchestral tribute to one of the most significant characters in Manga history. Composed by John Ottman—famed for his work on X-Men and Superman Returns—in association with Jeffrey Schindler, the score provides a grand, modern cinematic feel to the classic story. The lyrics pay homage to the original 1960s English-dubbed theme, bridging the gap between nostalgic fans and a new generation of viewers.
Loosely based on the legendary Manga series by Osamu Tezuka, the “God of Manga,” the 2009 movie produced by Imagi Animation Studios reimagines Toby Tenma’s transformation into the atomic-powered hero. The song’s references to being “atom celled” and “jet-propelled” are direct nods to the character’s unique robotic anatomy and his role as a “cosmic ranger” protecting the futuristic Metro City.
While the film updated the visuals for a global audience, the music, under the supervision of orchestrator Rick Giovinazzo, remained rooted in the hero’s hopeful and courageous spirit. The theme captures the essence of Astro Boy’s “flight into space” and his perpetual mission to prove that robots can possess a heart. Despite the film being a singular 2009 release, this theme continues to resonate as a “feel-good” anthem for the world’s most beloved robot boy.
