It's an invasion of Brad Pitt fans as thousands of people took over New York's Times Square for the premiere of Pitt's new movie World War Z.
The excitement is building for World War Z, a zombie movie unlike any you've ever seen.
People magazine's Sophie Schillaci told INSIDE EDITION, "Zombies have been around for a long time. They've been in the movies since the 1930's. Now, more than ever, they're extremely popular."
The zombie movie that started it all was the 1968 low-budget classic Night of the Living Dead. Director George Romero made the scarefest in Pittsburgh, recruiting locals as extras. The make-up was cheesy, the acting way over the top, but it's still one of the scariest movies ever made.
The sequel, Dawn of the Dead was set in a shopping mall. A bigger budget brought better special effects and more zombies.
Then, in 2002, the movie 28 Days Later upped the ante, introducing the fast zombie no one can outrun.
Zombies were played for laughs in 2004's Shaun of the Dead and in 2009's zombie apocalypse parody, Zombieland.
The Walking Dead brought zombies into our living rooms. The AMC series is the No. 1 drama on cable, combining soap opera with flesh-eating, slobbering zombies.
But World War Z may be the most terrifying zombie movie yet. These zombies are lightning fast. They swarm like bees and build a tower of zombies to attack.
"Zombies have always been threatening, but now they're invading. They're stronger. They're faster. Hollywood has really upped the ante," said Schillaci.
