Still no hard date for the release of the new Day of the Dead, but I did manage to find some production shots and a movie poster. There is a question about the origin of the poster - it may have been put together by a fan. My money is on it being a fan poster as it bears too similar a resemblance to one of the Land of the Dead posters to be real, but one never knows.

"When the world is overrun by the flesh hungry dead a small group of survivors head to an underground military bunker in a last ditch effort to stay alive."
