Jeremy Workman tracks an obsessive pedestrian in "The World Before Your Feet"

When Jeremy Workman learned his friend, Matt Green, planned to walk every street in New York City, Workman did what any sensible filmmaker would do: he grabbed his camera and followed along. Three years and 600 hours of footage later, Workman had everything he needed to tell the story of Green's unusual quest in Workman's film, The World Before Your Feet.
