Written, produced, and directed by Kent Mackenzie, this low-budget independent feature (1961) deserves to be ranked with John Cassavetes’s Shadows, but it languished unseen for nearly four decades until Thom Andersen celebrated it in his 2003 video essay Los Angeles Plays Itself. Pitched somewhere between fiction and documentary, with nonprofessional actors improvising postsynced dialogue and internal monologues, it follows a few uprooted Native Americans from Friday night to Saturday morning in the Bunker Hill district of Los Angeles. Its moving portraiture is refreshingly free of cliches and moralizing platitudes, and the high-contrast black-and-white photography and dense, highly creative sound track are equally impressive (even the occasional imprecise lip sync seems justified). Mackenzie lived only long enough to make one other feature–Saturday Morning (1971), which I haven’t seen–but this film’s lower-case urban poetry suggests a major talent. 72 min. Saturday 12/11, 3:30 PM, and Thursday 12/16, 8 PM, Gene Siskel Film Center.
