filmed on location in Peñíscola as the actual city had become modernized. For three months, hundreds of production design personnel constructed city walls to block off modern buildings. 1,700 trained infantrymen were leased from the Spanish Army as well as 500 mounted riders from Madrid's Municipal Honor Guard. 15 war machines and siege towers were constructed from historical artwork, and 35 boats were decorated with battlements to serve as the Moorish fleet. Tensions between Mann and Canutt rose as Mann sought to shoot the sequence himself. With the sequence nearly finished, Canutt spent three days filming pick-up shots, which would be edited within the longer, master shots that Mann had earlier shot. In his autobiography, Heston expressed his dissatisfaction with Mann's insistence on shooting the battle scenes himself, feeling Canutt was more competent and efficient. In April 1961, the last sequence to be shot for the film—the duel for Calahorra—was filmed near the Belmonte Castle. The scene was directed by Canutt. Prior to filming, Heston and British actor Christopher Rhodes trained for a month in the use in weaponry under stunt coordinator Enzo Musumeci Greco. The fight took five days to shoot, totaling 31 hours of combat before editing. 70,000 feet of film was shot for the sequence, which was ultimately edited down to 1,080 feet remaining in the film. Score The score was written by Miklos Rozsa, based on an extensive study of mediaeval Spanish music. The score has been re-recorded several times on its own and is regarded as one of the finest film scores. 20% of it was cut from the movie during post-production. Costume design Costume designers Veniero Colasanti and John Moore oversaw a staff of 400 wardrobe seamstresses which spent roughly $500,000 on manufacturing medieval-style clothing at a local supply company, Casa Cornejo, near Madrid. The most expensive costume piece was a black-and-gold velvet robe worn by King Alfonso VI during the film, which was tailored in Florence, Italy from materials specially woven in Venice. In total, over 2,000 costumes were used for the film. For the weaponry, Samuel Bronston Productions sought several local Spanish companies. Casa Cornejo provided 3,000 war helmets and hundreds of iron-studded leather jerkins. The Garrido Brothers factory, located in Toledo, Spain, worked under an exclusive contract for eight months producing 7,000 swords, scimitars, and lances. Anthony Luna, a Madrid prop manufacturer, crafted 40,000 arrows, 5,780 shields, 1,253 medieval harnesses, 800
