Once upon a time Detroit was the grand symbol of U.S. prosperity – the heart of the country's auto empire and the soul of its middle class. 

But the world changed, and now Detroit is a dying city, one where the population has dropped by 25 per cent in a few years and entire city blocks are being left to nature.re.

In Detropia, award-winning documentarians Rachel Grady and Detroit-born Heidi Ewing (Jesus Camp, The Boys of Baraka) explore what this demographic collapse means to the idea of the contemporary city. Drawing on interviews with the Mayor, city officials and those taking part in the largest internal migration in modern American history, Grady and Ewing seek to answer a most pivotal question: how do you run a city that no longer seems to have any reason to exist?

Thanks to ACMI, we have three double passes to give away to the Australian premiere of Detropia this Saturday October 20 at 4pm. This competition has now closed.
