Production has wrapped on the third installment in Gary Hustwit‘s design film trilogy. Funded mainly by the revenue from his first two feature-length documentaries, engaging explorations of typefaces (Helvetica) and stuff (Objectified), Hustwit’s latest effort tackles the design of cities. Urbanized will premiere next month at the Toronto International Film Festival (September 8-18) and make its U.S. debut on September 20 in New York City as part of Urban Design Week. “Unlike many other fields of design, cities aren’t created by any one specialist or expert,” says Hustwit, whose team filmed urban design projects in cities ranging from Detroit and New Orleans to Cape Town and Beijing. “There are many contributors to urban change, including ordinary citizens who can have a great impact improving the cities in which they live.” Urbanized will feature some such citizens, along with leading architects, planners, policymakers, and thinkers, including Norman Foster, Rem Koolhaas, Oscar Niemeyer, Amanda Burden, and Michael Sorkin. Stay tuned to the film’s website for an updated list of special screenings worldwide. Hustwit has already confirmed a slate of West Coast dates as well as events in Minneapolis, Austin, Indianapolis, and Columbus.
