From January 4 to 10 2011- France Télévisions shot a TV documentary about what one of the largest human concentrations in the world has become today: Mexico City urban agglomeration.The 7-day show focuses on a series of contrasted realities currently embracing the former aztec capital: the pursue for architectural branding, the valley’s ecological turmoil, shantytowns upgraded to municipal status, mega-uban programs, but also: interviewing intellectual elites, proactive religious extreme backers, wealthy upcoming Mexican entrepreneurs versus low-income youngsters couples, homosexual rights and gay marriage, illegal merchandise traffic, among others.During the France Télévisions documentary about Mexico City we sought the urge to have an overall view from different aspects on the ecologic chaos Mexico City's Valley suffer since its establishment back in the 16th century. The TV show also seeks to reveal the many aspects involved in this massive environmental issue: air pollution, soil sedimentation and erosion, diseases related to contaminated water, among many.We conducted a shooting at Netzahualcoyotl (Ciudad Neza), Mexico's largest localities. In it, Carmen Gomez (local labour worker) talks about Neza, and the bettered differences between Ciudad Neza 2 decades ago and today, and the impact she feels Neza has had on Mexico City's current renewed image.There were still many aspects to be shown about Mexico City. 25 years after the earthquake, 100 years after Mexican Revolution and 200 years away from our Independence. Nonetheless, I thoroughly believe this TV series provides a great opportunity for France Télévisions to be part of the renewing process of Mexico City's ethos, while featuring inspiring and compelling parts and phases that will spotlight next upcoming generations.
