'Us' Opens Up World Of Tunnels Underneath Society

The film “Us” starts off by saying the U.S. has thousands of miles of underground tunnels. This fact is true and has been documented by Will Hunt, author of “Underground: A Human History of the Worlds Beneath Our Feet.” According to SFGate, Hunt said “the scope of these tunnels would surprise you.” He said: “Wherever you go, there’s something under your feet that people don’t think about.” Hunt revealed there is a “massive community” of people living underneath cities.
