 Csupó reasons that the movie "deals with so many issues including friendship, and maybe first innocent love, things like that", so it "made more sense" to make the characters older.The film features a musical score by Aaron Zigman, who was hired after Alison Krauss backed out of the job.Zigman mentioned that there are similarities between the music he composed for "Bridge to Terabithia" and the film "Flicka" in that "...at times there's a bit of a Celtic influence but not much", but he also went on to say that there was a more modern feel to the music he composed for "Bridge to Terabithia".
