Rick Prelinger, father of public domain film, will show Panorama Ephemera, a feature-length collage film, at the San Francisco Cinematheque on Sunday, June 13 at 7:30 pm.

The film is made from "ephemeral film," which either were not copyrighted when originally published, or have passed into the public domain. The supply of such film officially ended in 1978, when all film is automatically (federally) copyrighted. (CORRECTED!)
