Shooting began on June 4, 2008, in Rome under the fake working title "Obelisk". The filmmakers scheduled three weeks of exterior location filming because of a predicted 2008 Screen Actors Guild strike on June 30. The rest of the film would be shot at Sony Pictures Studios in Culver City, California, to allow for this halt. Roman Catholic Church officials found "The Da Vinci Code" offensive and forbade filming in their churches, so these scenes were shot at Sony. The Caserta Palace doubled for the inside of the Vatican, and the Biblioteca Angelica was used for the Vatican Library. Filming took place at the University of California, Los Angeles in July. Sony and Imagine Entertainment organized an eco-friendly shoot, selecting when to shoot locations based on how much time and fuel it would save, using cargo containers to support set walls or greenscreens, as well as storing props for future productions or donating them to charity.
