According to an interview with Neil Gaiman, the original computers used to do all of the CG were named after The Beatles (John, Paul, Ringo, George). Later a fifth computer was required, so it was named Yoko. Soon after the fifth computer was introduced, the network crashed and could not be restored properly ("the computers refused to talk to each other"). A new server and computers were purchased and named after The Ramones (Joey, Jonny, DeeDee and Tommy). Gaiman said "I wish I knew more about the history of The Ramones; the computers performed brilliantly, vibrantly and died an untimely - and early - death"
During the circus montage at the beginning of the film, there is a brief shot of a hand balancing and twirling a set of four crystal balls. This art is called Contact Juggling, created by performance artist Michael Moschen and originally debuted in the Jim Henson film Labyrinthe (1986), which in part inspired this film.
According to Neil Gaiman, this film was made as a straight-to-DVD film; but this film finally got a limited theatrical release in the United States.
