around regulations on how far they could be shot during filming. They also used 2,000 live actors to create a computer-generated crowd of 35,000 virtual actors that had to look believable and react to fight scenes. The Mill accomplished this by shooting live actors at different angles giving various performances, and then mapping them onto cards, with motion-capture tools used to track their movements for three-dimensional compositing. The Mill created over 90 visual effects shots, comprising approximately nine minutes of the film's running time. An unexpected post-production job was caused by the death of Oliver Reed of a heart attack during the filming in Malta before all his scenes had been shot. The Mill created a digital body double for the remaining scenes involving his character Proximo by photographing a live-action body double in the shadows and by mapping a three-dimensional computer-generated imagery mask of Reed's face to the remaining scenes during production at an estimated cost of $3.2 million for two minutes of additional footage. Visual effects supervisor John Nelson reflected on the decision to include the additional footage: "What we did was small compared to our other tasks on the film. What Oliver did was much greater. He gave an inspiring, moving performance. All we did was help him finish it." The film is dedicated to Reed's memory. Music The Oscar-nominated score was composed by Hans Zimmer and Lisa Gerrard, and conducted by Gavin Greenaway. Zimmer was originally planning to use Israeli vocalist Ofra Haza for the score, after his work with her in The Prince of Egypt. However, Haza died in late February 2000, before she was able to record, and so Gerrard was chosen instead. Lisa Gerrard's vocals are similar to her own work on The Insider score. The music for many of the battle scenes has been noted as similar to Gustav Holst's "Mars: The Bringer of War", and in June 2006, the Holst Foundation sued Hans Zimmer for allegedly copying the late Holst's work. Another close musical resemblance occurs in the scene of Commodus's triumphal entry into Rome, accompanied by music clearly evocative of two sections – the Prelude to Das Rheingold and Siegfried's Funeral March from Götterdämmerung – from Richard Wagner's Ring of the Nibelung. On February 27, 2001, nearly a year after the first soundtrack's release, Decca produced Gladiator: More Music From the Motion Picture. Then, on September 5, 2005, Decca produced
