– Film Summary –

THE CITY DARK chronicles the disappearance of darkness. The film follows filmmaker (and amateur astronomer) Ian Cheney, who moves to New York City from Maine and discovers urban skies almost completely devoid of stars. Posing a deceptively simple question, “What do we lose, when we lose the night?” the film leads viewers on a quest to understand how light pollution is affecting people and the planet. In six chapters weaving together cutting-edge science with personal, meditative sequences reflecting on the human relationship to the sky, THE CITY DARK shines a new light on the meaning of the dark.

I. The City Bright
In New York City, we meet Irve Robbins, a Brooklyn-born astronomer running one of the last remaining observatories in New York City, where he is limited to showing his students only the brightest objects that shine through the city’s light-polluted sky. As Robbins puts it, “I’ve seen twice the Milky Way in New York — when there was a blackout.” At a Hackensack warehouse filled with thousands of different light bulbs, Larry Birnbaum explains the evolution of electric lights since Edison’s first tungsten bulb, noting that each successive generation sought to maximize its light output; today, lights produce thousands more lumens than Edison’s original. As city lights grew brighter, and cities themselves grew bigger, fewer and fewer young people grew up with a connection to the stars. Neil deGrasse Tyson, a leading astrophysicist who grew up in the Bronx, describes falling in love with the stars during his first visit to the Hayden Planetarium in Manhattan, and notes the irony of falling in love with an artificial night sky — in the Bronx, after all, there were never more than a few dozen stars.

II. Islands of Dark
Seeking the astronomers who have fled cities for darker skies, the filmmaker finds his way to rural Arizona, just a stone’s throw from the Mexico border, where a community of stargazers have established “Sky Village,” a haven for astronomy and darkness. The astronomers struggle to put into words what drew them to the stars, but time-lapse photography of the Milky Way says it all — it’s one of the clearest views of the universe available in the United States. One of the other best places for stargazing – and said to be the best professional astronomy site in the world – is under threat, on the islands of Hawai’i. Here, astronomers’ attempts to detect earth-killing asteroids with the world’s newest, largest camera are frustrated by urban population growth in the cities below. As Nick Kaiser of the University of Hawai’i puts it, “it’s as though you’re looking through fog.” A brief animation sequence reveals the haze of light that is covering much of the
planet; a study by researchers in Italy yielded the revelation that 2/3 of all humans now live under skies polluted by artificial light. In their words, “mankind is proceeding to envelop himself in a luminous fog.”

III. Nature and the Night
As it turns out, astronomers are not the only ones losing the night. Biologists along the Florida coast trace the death of thousands of hatching sea turtles due to their disorientation by Miami’s lights. Volunteers at the Field Museum in Chicago collect thousands of dead birds from the city sidewalks, victims of light-induced disorientation and collisions into brightly-lit buildings. As Chad Moore of the National Park Service explains, “When we add light to the environment, that has the potential to disrupt habitat, just like running a bulldozer over the landscape can.” Which raises the question: do humans need the dark?

IV. Night Shifts
Suzanne Goldklang, a breast cancer patient who for years worked a night shift selling jewelry on late night TV, says she spends little time wondering what gave her cancer. But epidemiologist Richard Stevens of the University of Connecticut has been struggling for his entire career to understand why women in industrialized societies suffer from increased rates of breast cancer. In 1987, he woke up in the middle of the night staring at the streetlight pouring in his window, and became the first to suggest a link between light at night and breast cancer. Stevens’ research led to the revelation that night shift workers are almost twice as likely to develop breast cancer, suggesting that disrupted circadian rhythms cause us more harm than we might think.

V. Why We Light
But don’t we need lights? The filmmaker recalls his childhood home in Maine being
broken into by thieves; his family responded by installing an enormous bright light on the corner of the barn. Historian Roger Ekirch confirms that humans have long feared the dark, and that crime was the original impetus for widespread street lighting on the planet. In Newark, New Jersey, a criminologist shows how city parks have pushed back crime by introducing bright new lampposts; residents agree that lights have made the community more livable and sociable, and the film tilts towards an exploration of the human attraction to light. As author Jane Brox puts it, “the struggle to create more and more light was a struggle to dominate the night, rather than be dominated by the night.”

VI. Astrophilia
And yet, as Cheney notes from his rooftop in Brooklyn, “though we may love the light, we may also need the dark.” In the film’s last chapter, we encounter the ways in which lighting designers – atop the Highline in Manhattan, and in a tiny rural Maine town – are balancing the human love of light with our need for darkness, our love of the starry skies, and our desire to cut energy costs with more efficient designs. In a final montage of starry skies, we hear remembrances from the film’s interviewees, recalling their first experience seeing the heavens; Neil deGrasse Tyson, the Queens-born astrophysicist has the final word: “when you look at the night sky, you realize how small we are within the cosmos. It’s kind of a resetting of your ego. To deny yourself of that state of mind, either willingly or unwittingly…is to not live to the full extent of what it is to be human.”

– BIO –

Ian Cheney is a Brooklyn-based documentary filmmaker. He grew up in New England and earned his Bachelor’s and Master’s degrees at Yale. After graduate school he cocreated and starred in the Peabody Award-winning theatrical hit and PBS documentary King Corn (2007), directed the feature documentary The Greening of Southie (Sundance Channel, 2008), and co-produced the Planet Green film Big River (2009). Ian maintains a 1/1000th acre farm in the back of his ’86 Dodge pickup, which is at the center of his recent film Truck Farm (2011). He has been featured in the New Yorker, the New York Times, on CNN and on Good Morning America. An avid astrophotographer, he travels frequently to show his films, lead discussions and give talks about sustainability, agriculture, and the human relationship to the natural world.

– DIRECTOR Q&A –

What led to the making of THE CITY DARK?
Most of the photographs I took when I was a kid were taken at night. Spending a lot of my childhood in rural Maine, I fell in love with the night sky and wanted to try and capture it as best I could. I used a Pentax camera borrowed from my Dad, a high school photography teacher, and experimented with different long exposures using an unforgivable amount of Dad’s Kodak Gold film. And spending so many nights out under the stars, I became something of an amateur astronomer as a teenager, even building my own telescope out of an old cardboard construction tube. But as I grew up and spent more and more time in cities, my connection to the stars faded. If I paused to wonder what this disconnection meant, I couldn’t put it into words, and rarely thought if mattered much. Why would we need the stars? But then a few years ago, I heard that someone calculated that for the first time in history, the world was now a predominantly urban population, with more of us living in cities than in the countryside. It occurred to me that my own migration from countryside to city – and from dark, starry skies to bright, electric lights – mirrored the world’s demographic shift in a rather startling way. With so few of us growing up with a connection to the stars, might we be losing something rather fundamental? The more I thought about it, the more I felt I had lost something — something I couldn’t put my finger on.

And how did the film evolve?
I started with a simple question: “why do we need the stars?” And clearly the first people to talk to were astronomers. And though they wove together an impressive array of astronomy-based answers for why we should be able to see a clear night sky – to detect earth-killing asteroids, say, or to discover what the universe is actually made of – many of them pushed me towards thinking outside the observatory, in two main ways. First, it was clear that many of the astronomers I spoke to, especially the unpaid amateur astronomers, felt a kind of spiritual or emotional connection to the stars, much the way a person might feel an affection for a beautiful mountain, ocean view, or city park. Are the stars part of nature? How can we define what we gain from seeing the universe? Does human culture somehow need the context of the greater cosmos, to help us keep things in perspective? These intangible lines of inquiry became the undercurrent of the film, alongside another realm of inquiry that the astronomers pushed me towards: the science of the night. Given that the planet earth has evolved for billions of years with a very consistent rhythm of light and dark, might the sudden introduction of electric light affect more than our view of the stars? THE CITY DARK also engages the relatively new field of the ecology of the night in an attempt to understand how our loss of darkness is affecting humans and wildlife. In all, the visual treatment of the film carries these two lines of inquiry forward by weaving together more poetic, meditative footage of the night sky with handheld footage of real people exploring these issues by day.
