"Spartacus" was filmed using the 35 mm Super 70 Technirama format and then blown up to 70 mm film. This was a change for Kubrick, who preferred using the standard spherical format. This process allowed him to achieve ultra-high definition and to capture large panoramic scenes. Kubrick had wanted to shoot the picture in Rome with cheap extras and resources, but Edward Muhl, president of Universal Pictures, wanted to make an example of the film and prove that a successful epic could be made in Hollywood itself and "stem the flood of 'runaway' producers heading for Europe". A compromise was reached by filming the intimate scenes in Hollywood, and the battle scenes, at Kubrick's request, in Spain. Kubrick found working outdoors or in real locations to be distracting; he believed the actors would benefit more from working on a sound stage, where they could fully concentrate. To create the illusion of the large crowds that play such an essential role in the film, Kubrick's crew used three-channel sound equipment to record 76,000 spectators at a Michigan State – Notre Dame college football game shouting "Hail, Crassus!" and "I'm Spartacus!"
