Nagaoka's film features new character designs by Katsuyuki Kubo and features a score composed by Michael Nyman, including two songs, "If" (which incorporates "Time Lapse" from A Zed & Two Noughts) and "Why," which have become concert works. The former also appeared in an altered form in the film, The Libertine. The singer is contraltoHilary Summers. "Candlefire" as well as piano-only versions of "If" and Why" appear on Nyman's 2005 release, The Piano Sings.
Anime News Network's Justin Sevakis said that "even a story as powerful as Anne Frank's cannot overcome truly odious filmmaking and weird directorial choices that just don't work" and that he couldn't "think of a worse way to experience the story than watching this film".
