Question: What is the GDP of the city where Spectre was filmed after filming where Giovanni Gronchi died?

<P0-S0> 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. <P0-S1> 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. <P0-S2> This particular scene in Mexico required 1,500 extras, 10 giant skeletons and 250,000 paper flowers. <P0-S3> 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. <SEP> <P1-S0> Mexico City is one of the most important economic hubs in Latin America. <P1-S1> The city proper (Federal District) produces 15.8% of the country's gross domestic product. <P1-S2> 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). <P1-S3> Excluding the rest of the Mexican economy, Mexico City alone would rank as the 30th largest economy in the world. <P1-S4> 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%). <P1-S5> 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. <P1-S6> Mexico City has one of the world's fastest-growing economies and its GDP is set to double by 2020. <SEP> <P2-S0> after wrapping up in england, production travelled to morocco in june, with filming taking place in oujda, tangier and erfoud, after preliminary work was completed by the production's second unit. <P2-S1> an explosion filmed in morocco holds a guinness world record for the "largest film stunt explosion" in cinematic history, with the record credited to production designer chris corbould. <P2-S2> principal photography concluded on 5 july 2015. a wrap-up party for spectre was held in commemoration before entering post-production. <P2-S3> filming took 128 days. <SEP> <P3-S0> The unhappy Tambroni experiment tarnished Gronchi’s reputation for good, and until the end of his period of office he remained a lame-duck President. <P3-S1> In 1962 he attempted to get a second mandate, with the powerful help of Enrico Mattei, but the attempt failed and Antonio Segni was elected instead. <P3-S2> As he ceased to be Head of State, he became a life senator by right, according to the Italian Constitution. <P3-S3> He died in Rome on 17 October 1978 at the age of 91. <SEP> <P4-S0> bond disobeys m's order and travels to rome to attend sciarra's funeral. <P4-S1> that evening he visits sciarra's widow lucia, who tells him about spectre, a criminal organisation to which her husband belonged. <P4-S2> bond infiltrates a spectre meeting, where he identifies the leader, franz oberhauser. <P4-S3> when oberhauser addresses bond by name, he escapes and is pursued by mr. hinx, a spectre assassin. <P4-S4> moneypenny informs bond that the information he collected leads to mr. white, former member of quantum, a subsidiary of spectre. <P4-S5> bond asks her to investigate oberhauser, who was presumed dead years earlier.
