Film Screening: Microcosmos
Saturday, August 10, 7 p.m.
Microcosmos (1996), 80 minutes
A captivating documentary — now a world-renown classic — written and directed by Claude Nuridsany and Marie Pérennou, this extraordinary and awe-inspiring film takes a very close look at the life of invertebrates. Film critic Roger Ebert writes, “The movie is a work of art and whimsy, as much as one of science. It uses only a handful of words, but is generous with music and amplified sound effects, dramatizing the unremitting struggle of survival that goes on in a meadow in France.”
Tickets for Microcosmos are pay-what-you-wish.
