Codirected by Chris Marker and Mario Marret, this 1968 film (recently released on video) focuses on workers at a textile factory in Besancon. Their brief strike, expressing solidarity with some comrades who’ve been laid off, is apparently not a success, but the film ends by emphasizing that they’re “learning.” Marker’s agitprop is always subtler than it seems; the opening, in which a handheld camera circles an organizer as he gathers a crowd, is as stylish as it is committed. Laborers describe the toll taken by the repetitive tasks and shift changes, but even here Marker includes his characteristic diversions—as they discuss making revolution, you can hear a baby crying. 39 min.
