Dawn of the Dead (also known internationally as Zombi) is a 1978 American horror film directed by George A. Romero. It was written by Romero in collaboration with the Italian filmmaker Dario Argento, and produced by Claudio Argento, Richard P. Rubinstein and Alfredo Cuomo. It was the second film made in Romero's Living Dead series, but contains no characters or settings from Night of the Living Dead, and shows in a larger scale the apocalyptic effects on society. In the film, a phenomenon of unidentified origin has caused the reanimation of the dead, who prey on human flesh, which subsequently causes mass hysteria. The cast features David Emge, Ken Foree, Scott Reiniger, and Gaylen Ross as survivors of the outbreak who barricade themselves inside a suburban shopping mall.
