Barbet Schroeder · 1978
Barbet Schroeder’s 1978 documentary observes Francine Patterson’s work teaching American Sign Language to Koko the gorilla at Stanford University. Shot by Néstor Almendros in restrained, natural light, it avoids explanation or advocacy, instead holding sustained, quiet attention on Koko’s signing, expressions, and interactions. It engages with questions of animal personhood, the ethics of observation, and the limits of human language — not as arguments, but as durational encounters. Released by New Yorker Films in the US and later restored by Criterion, it remains a singular, understated work in the history of science-facing documentary.
