"Night of the Living Dead" is the first modern zombie movie and first horror movie to have a black man as a main character.

The film was completed on a $114,000 budget and shot outside Pittsburgh, where it had its theatrical premiere on October 1, 1968. The film grossed $12 million domestically and $18 million internationally, earning over 250 times its budget. Night of the Living Dead has been regarded as a cult classic by film scholars and critics, despite its being heavily criticized upon its release for its explicit gore. It eventually garnered critical acclaim and has been selected by the Library of Congress for preservation in the National Film Registry, as a film deemed "culturally, historically, or aesthetically significant"

Night of the Living Dead (1968) is definitely a historical hallmark film.

Directed by George A. Romero. With Duane Jones, Judith O'Dea, Karl Hardman, Marilyn Eastman.
