Principal photography concluded on 5 July 2015. A wrap-up party for Spectre was held in commemoration before entering post-production. Filming took 128 days.
Document 4: Economy of Mexico: The economy of Mexico is the 13th largest in the world in nominal terms and the 11th largest by purchasing power parity, according to the International Monetary Fund. Since the 1994 crisis, administrations have improved the country's macroeconomic fundamentals. Mexico was not significantly influenced by the 2002 South American crisis, and maintained positive, although low, rates of growth after a brief period of stagnation in 2001. However, Mexico was one of the Latin American nations most affected by the 2008 recession with its Gross Domestic Product contracting by more than 6% in that year.

Document 8: Roman Republic: Tiberius' brother Gaius was elected tribune in 123 BC. Gaius Gracchus' ultimate goal was to weaken the senate and to strengthen the democratic forces. In the past, for example, the senate would eliminate political rivals either by establishing special judicial commissions or by passing a senatus consultum ultimum ("ultimate decree of the senate"). Both devices would allow the Senate to bypass the ordinary due process rights that all citizens had. Gaius outlawed the judicial commissions, and declared the senatus consultum ultimum to be unconstitutional. Gaius then proposed a law which would grant citizenship rights to Rome's Italian allies. This last proposal was not popular with the plebeians and he lost much of his support. He stood for election to a third term in 121 BC, but was defeated and then murdered by representatives of the senate with 3,000 of his supporters on Capitoline Hill in Rome. Though the senate retained control, the Gracchi had strengthened the political influence of the plebeians.

Document 10: Spectre (2015 film): A brief shoot at London's City Hall was filmed on 18 April 2015, while Mendes was on location. On 17 May 2015 filming took place on the Thames in London. Stunt scenes involving Craig and Seydoux on a speedboat as well as a low flying helicopter near Westminster Bridge were shot at night, with filming temporarily closing both Westminster and Lambeth Bridges. Scenes were also shot on the river near MI6's headquarters at Vauxhall Cross. The crew returned to the river less than a week later to film scenes solely set on Westminster Bridge. The London Fire Brigade was on set to simulate rain as well as monitor smoke used for filming. Craig, Seydoux, and Waltz, as well as Harris and Fiennes, were seen being filmed. Prior to this, scenes involving Fiennes were shot at a restaurant in Covent Garden. Filming then took place in Trafalgar Square. In early June, the crew, as well as Craig, Seydoux, and Waltz, returned to the Thames for a final time to continue filming scenes previously shot on the river.

Document 12: Mexico City: Mexico City is Latin America's leading center for the television, music and film industries. It is also Mexico's most important for the printed media and book publishing industries. Dozens of daily newspapers are published, including El Universal, Excélsior, Reforma and La Jornada. Other major papers include Milenio, Crónica, El Economista and El Financiero. Leading magazines include Expansión, Proceso, Poder, as well as dozens of entertainment publications such as Vanidades, Quién, Chilango, TV Notas, and local editions of Vogue, GQ, and Architectural Digest.
Document 13: Spectre (2015 film): With filming completed in Rome, production moved to Mexico City in late March to shoot the film's opening sequence, with scenes to include the Day of the Dead festival filmed in and around the Zócalo and the Centro Histórico district. The planned scenes required the city square to be closed for filming a sequence involving a fight aboard a Messerschmitt-Bölkow-Blohm Bo 105 helicopter flown by stunt pilot Chuck Aaron, which called for modifications to be made to several buildings to prevent damage. This particular scene in Mexico required 1,500 extras, 10 giant skeletons and 250,000 paper flowers. Reports in the Mexican media added that the film's second unit would move to Palenque in the state of Chiapas, to film aerial manoeuvres considered too dangerous to shoot in an urban area.
Document 14: Mexico City: Mexico City is one of the most important economic hubs in Latin America. The city proper (Federal District) produces 15.8% of the country's gross domestic product. According to a study conducted by PwC, Mexico City had a GDP of $390 billion, ranking it as the eighth richest city in the world after the greater metropolitan areas of Tokyo, New York City, Los Angeles, Chicago, Paris, London and Osaka/Kobe (and the richest in the whole of Latin America). Excluding the rest of the Mexican economy, Mexico City alone would rank as the 30th largest economy in the world. Mexico City is the greatest contributor to the country's industrial GDP (15.8%) and also the greatest contributor to the country's GDP in the service sector (25.3%). Due to the limited non-urbanized space at the south—most of which is protected through environmental laws—the contribution of the Federal District in agriculture is the smallest of all federal entities in the country. Mexico City has one of the world's fastest-growing economies and its GDP is set to double by 2020.
Document 15: Spectre (2015 film): Whilst filming in Mexico City, speculation in the media claimed that the script had been altered to accommodate the demands of Mexican authorities—reportedly influencing details of the scene and characters, casting choices, and modifying the script in order to portray the country in a "positive light"—in order to secure tax concessions and financial support worth up to $20 million for the film. This was denied by producer Michael G. Wilson, who stated that the scene had always been intended to be shot in Mexico as production had been attracted to the imagery of the Day of the Dead, and that the script had been developed from there. Production of Skyfall had previously faced similar problems while attempting to secure permits to shoot the film's pre-title sequence in India before moving to Istanbul.
