Louis Alvarez and Andrew Kolker won their first Peabody in 1988 for American Tongues, a film about the differences in the way Americans speak and the attitudes people have about regional and social accents. It was the very first film broadcast on POV. In 1992, POV premiered Louisiana Boys (co-produced by Paul Stekler). For over the past 35 years, Alvarez and Kolker have produced critically praised documentaries for their production companies, Kingfish Productions and The Center for New American Media. In this extended interview that is part of our new Behind the Lens series, they talk about the work they started doing in the 1980s, the challenges facing documentary filmmakers at that time, and how nonfiction filmmaking has evolved over the past three decades.
