James Horner seems to excel when writing for children films. His scores for animated films, such as An American Tail and Balto are all very enjoyable, as is this charming and beautiful score for Casper. As innocent and kind as the friendly ghost Casper, the majority of the music for this film is cute and soft, like the stunning "Casper's Lullaby", which features a wonderful rendition of Casper's theme, performed by piano, strings and wordless choir. And the bitter sweet "Fond Memories", a little depressing but oh, so beautiful.
But the score also boasts some great fun. Especially when Casper's uncles are on screen. These three ghosts are portraid with groovy and wild jazz music. And the villains have been given an entertaining march, heard in "Carrigan & Dibs" and the quirky "March of the Exorcists". "First Haunting/The Swordfight" includes some grand adventurous music, complete with choir, Horner's crashing piano, hammond organ, and with quotes from the score for The Sea Hawk - an inside joke for those familiar with Korngold's score.
In short, Casper is a very entertaining score, with both lush, sweeping music, as well as more upbeat parts - there is something for everyone on this soundtrack. Apart from Horner's score, the soundtrack includes two pop songs, being "Remember Me This Way", performed by Jordan Hill and "Casper the Friendly Ghost", sung by Little Richard.
