Lost Rivers – OFFICIAL TRAILER from Catbird Productions on Vimeo.

Catbird Productions put out this trailer for their film Lost Rivers which talks about the history of rivers to the formation and cities and how over time we have covered them completely and encased them in tunnels to build on top of them. Now, groups in cities all over the world are trying to find some of them and unearth them once more so that these waters can see daylight.
