 Marc Singer (qv) had never been a filmmaker prior to this project.  He had moved underground to the tunnels as a lifestyle choice, and  when he and his friends were sitting around one night, someone had  said, according to Singer, "Hey we should make a film about this,"  and tell their stories. Singers original hope was that the film  would get some attention and help get the people out of the tunnels  and into better, safer places. It did.
