"Night of the Living Dead" entered the public domain in the United States because the original theatrical distributor, the Walter Reade Organization, failed to place a copyright indication on the prints, and at that time, United States copyright law held that public dissemination required copyright notice to maintain a copyright. Image Ten displayed such a notice on the title frames of the film beneath the original title, "Night of the Flesh Eaters", but the distributor erroneously removed the statement when it changed the title.
