Visionary filmmaker Rolf Forsberg's impressionistic and often mind-boggling short films were seen by millions on the big screen, in classrooms, and in churches during the 1960s and 70s. Many recall Forsberg's cinematic spiritual explorations for their audacity and stark images. Here are four Forsberg masterworks, each introduced by the filmmaker himself:

Parable (1964) 23m. Forsberg's critically acclaimed, controversial Parable was the main attraction at the Protestant and Orthodox Pavilion of the 1964 New York World's Fair. A mysterious clown in all white attire appears as a Christ-like figure to redeem a circus. Restored to its original widescreen format.

The Antkeeper (1966) 28m. The story of mankind is represented by a gardener, his son, the wicked one, and a world populated by ants. Drawing inspiration from the works of Fellini and Bergman, this is Forsberg's thought-provoking 1960s cinematic metaphor with breathtaking imagery and mind-blowing ant photography by the distinguished macro-cinematographer Robert Crandall.

Ark (1970) 20m. Forsberg's prophetic vision of environmental and spiritual degradation depicts one man's desperate attempt to protect a sealed ecosystem from hostile intruders.

One Friday (1973) 10m. A day like any other Friday, only an all-out-race war is underway today and no one in this upscale neighborhood is safe, not even a young child whose purity and innocence serves as counterpoint to the chaotic turmoil unfolding all around him.
