Motion picture films don’t last forever; many have already been lost or destroyed. For almost two decades, we’ve worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies — including home movies, industrial films, and other non-fiction. If you have endangered films you’d like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we’d love to hear from you.
