Ian Cheney's The City Dark, which premiered on POV on July 5, 2012, has prompted viewers to share their own stories about the night sky.

In July 2012, POV caught up with filmmaker Ian Cheney of 'The City Dark' to find out how the film has been received, and changes he's seen people making in order to combat light pollution.

We love Ian Cheney's stunningly beautiful, humorous and informative film about the effects of light pollution on our bodies, minds and skies — and critics do, too.

POV's 25th season continues with a documentary that explores the physical and psychological effects of light pollution.
