Since at least the 1940s, the San Francisco Bay Area has been one of the world’s epicenters of personally expressive filmmaking and community-focused non-mainstream film culture. At the close of a tumultuous and even traumatic year, Cinematheque culminates its 2020 exhibitions with Commingled Containers: Echoes from a Bay, two guest-curated programs highlighting recent works by Bay Area filmmakers and celebrating the continuously-renewing, ever-evolving traditions of the region’s vibrant artist communities.
