This spring, the David Rockefeller Center for Latin American Studies at Harvard University launched a series of conferences focused on Mexico City. Entitled “Entornos Urbanos” (Urban Environs), these events highlight ongoing research at Harvard in the areas of public health, environment, and urban design, using Mexico City as a case study. Parallel to the conference, the Center and Harvard Film Archive have organized the following selection of films that feature Mexico City as their locale or theme. Contrasting two films from the 1950s by Luis Buñuel with a trio of contemporary works, we attempt to shed some cinematic light on issues—both enduring and altered—that the city has faced across the last half century.
