The multiplexes keep multiplying, but they're all showing the same Adam Sandler and Lindsay Lohan atrocities. True cineastes know that Denver's central library can be counted on for filmfests that mix the traditional and the edgy, the classic and the avant-garde. Past offerings have included the films of Billy Wilder, horror flicks, gay cinema, notable adaptations of great novels and a selection of top-drawer items from the "golden year of film," 1939. They're all free, often hosted by online film critic Walter Chaw -- and there's even popcorn for sale.
