Dawn of the Dead
In 1978, George A. Romero released Dawn of the Dead as a follow-up to his 1968 classic, Night of the Living Dead (the forerunner of all modern zombie films). While Romero gets a writing credit for this movie based on his original 1978 screenplay, and there are definitely some similarities here, it’s not the same movie.
Directed by Zack Snyder, and still taking place in a shopping mall as the zombies start to make their presence felt throughout the world, there is a definite shift over thirty years. Where the first film left you to do a bit more interpreting, and was a bit more on the psychological side, this one is a bit more a sign of the times, and gives you a lot more action to work with while you watch the affect of being cooped up as the world crumbles.
