Day of the Dead is a very, very loose remake of George A. Romero's 1985 film. It has a number of differences. The newer zombies are able to run and climb walls, unlike the lumbering zombies from Romero's film. The bunker from the original appears in only the last part of the 2008 movie. And so on. The newer film could be called a "reimagining," rather than a remake.
