From wikipedia.org
"Night of the Living Dead (1968) is a seminal horror film directed by George A. Romero which was to transfigure the horror-movie genre. The plot is simple and familiar to viewers even casually acquainted with the genre: the dead come to life, spreading their condition through the United States and attacking the living in order to feed upon their flesh. It was filmed in Evans City, Pennsylvania.
Although a low budget film (it cost around $114,000 to produce) and helmed by a first-time director, the film is considered a horror classic by many film critics, and placed #93 on the American Film Institute's 100 Years, 100 Thrills list. It was shot in black and white, and employed cost-saving special effects as using Bosco chocolate syrup as cinema blood. Extras working on the film got one dollar and a T-Shirt Stating "I Was A Zombie In Night of the Living Dead!""
