'Night of the Living Dead': How a 42-year-old zombie movie refuses to die; Entertainment Weekly, 10/28/10

Clark Collis, Entertainment Weekly; 'Night of the Living Dead': How a 42-year-old zombie movie refuses to die:

"Alas, by then, Night of the Living Dead had fallen into the public domain, which meant the film’s rights were of extremely limited use and worth. In fact, as far as the U.S. Copyright Office was concerned, the movie had always been in the public domain. This was the fault of the Walter Reade Organization, who neglected to put a copyright notice on the title card of the movie after the name change to Night of the Living Dead. “It was our first film; we didn’t know what we were doing,” says Romero. “When they took that title off and replaced it with Night of the Living Dead, they didn’t put the copyright bug there because it normally shouldn’t be there. It should be at the end of the film.”"
