have that." Reportedly, "cost overruns and production nightmares" led the studio to "reconsider their commitment to feature animation." Filmmaker Brad Bird (who helmed The Iron Giant, Warner Bros.' next animated film) thought that micromanaging, which he said had worked well for Disney but not for Warner Bros., had been part of the problem. Animation The film was mainly animated at the main Warner Bros. Feature Animation facility located in Glendale, California and London, England. In January 1996, the London animation studio was opened where more than 50 animators were expected to animate 20 minutes of animation, which would be sent back to Glendale to be inked-and-painted. Additional studios that worked on the film included Yowza! Animation in Toronto, Ontario, where they assisted in clean-up animation, Heart of Texas Productions in Austin, and A. Film A/S in Copenhagen where, along with London, about a quarter of the film was animated overseas. The supervising animators were Athanassios Vakalis for Kayley, Chrystal Klabunde for Garrett, Cynthia Overman for Juliana, Alexander Williams for Ruber, Dan Wagner for Devon and Cornwall, Stephan Franck for the Griffin and Bladebeak, and Mike Nguyen for Ayden. To create the rock-like ogre and other computer-generated effects, the production team used Silicon Graphics' Alias Research software. According to Katherine Percy, the head of CGI effects, the software was originally designed for special effects used in live-action films. Music On January 31, 1996, Carole Bayer Sager and David Foster were attached to compose several songs for the film. The album peaked at #117 on the Billboard 200, and won the Golden Globe Award for Best Original Song for "The Prayer". The song was also nominated for the Academy Award for Best Original Song, though it lost to "When You Believe" from DreamWorks' The Prince of Egypt. On the soundtrack, "The Prayer" was performed separately by Celine Dion in English, and by Andrea Bocelli in Italian. The now better-known Dion-Bocelli duet in both languages first appeared in October 1998 on Dion's Christmas album These Are Special Times; it was also released as a single in March 1999 and on Bocelli's album Sogno in April 1999. "Looking Through Your Eyes" was the lead single for the soundtrack. Other original songs composed for the film include "United We Stand", "On My Father's Wings", "Ruber", "I Stand Alone", and "If I Didn't Have You". The soundtrack also includes pop versions of "Looking Through Your Eyes"
