An “act of conscience” on the part of seven left-wing French filmmakers—Jean-Luc Godard, Alain Resnais, Ruy Guerra, Agnes Varda, Michele Ray, William Klein, and Chris Marker. Although dated as propaganda, it’s still one of the most effective political documentaries ever made, assembled one year before the deluge of theoretical abstraction that descended in 1968. In French with subtitles.
