Luis Ospina (The Vampire of Poverty, Paper Tiger) turns the camera toward his radical roots—and his own intestines—for this documentary about the Cali Group, the Colombian artists’ collective that revolutionized art, cinema, and literature amid drug-related terrorism in the 1970s and ’80s. Boasting a wide array of never-before-seen archival material, Ospina (the group’s only surviving member, who was diagnosed with cancer during the making of the film) focuses on telling the stories of co-founders Andrés Caicedo and Carlos Mayolo. Never maudlin or self-important, this kaleidoscopic inside view of “Caliwood” is essential viewing for anyone looking for darkly comic, anarchic inspiration.
