I talked with actor/writer/director Emilio Estevez about his latest film, 'The Public,' set in a Cincinnati library during a brutal cold snap. The librarians are thrust into the roles of first responders and social workers, helping the homeless who come there for shelter.  And on this lethally cold night, the homeless refuse to leave at closing time, leading to a confrontation with police. Estevez produced, directed, wrote and stars in the film, alongside a great cast. And the project came about after Estevez learned of the challenges libraries and librarians face these days, and not just from technological change. Estevez and I were joined in our conversation by Rich Hull, CEO of Pongalo, the Spanish-language video service that partly backed the film. There's lots to talk about when it comes to libraries and their importance as one of the basic building blocks in democracy. Give a listen.
