Summary

• Through films like Night of the Living Dead and Train to Busan, zombies have evolved to represent society's deepest fears and anxieties.
• The horror genre has explored different types of zombies, from slow-moving Ghouls to bio-engineered creatures, each more terrifying than the last.
• From Nazi zombies to infected masses, each zombie subgenre offers unique scares, touching on themes of societal collapse and personal survival.

From mindless brain-eating Ghouls to intelligent herd-moving masses, the zombie has always been one of the most terrifying creatures in the entire horror movie genre. As a supernatural threat that delved right into the most innate of human fears, the zombie has always represented society's angst about the other and the clamoring terror of those who seek to invade spaces and take over the minds of populations. Often a powerful symbol of cultural and political anxieties, the undead nature of the zombie has for generations made viewers' skin crawl as they covered their eyes in abject terror.

The most common perception of the modern zombie came from George A. Romero’s Night of the Living Dead in 1968, as slow-moving, mindless Ghouls pursued their victims in an endless chase where death felt like a sad inevitability. As the decades ed, the zombie genre grew to include fast-moving zombies, innocent victims destroyed by all-consuming viruses, and even those who lost their humanity due to demonic possession. In the history of horror, there have been so many frightful, terrifying, and scary zombies.

Night of the Living Dead (1968)

With six installments all directed by Romero, following his death in 2017, a seventh film based on a treatment he wrote called Twilight of the Dead has been announced.

8 The Buckner Family

6 Shamblers and Alphas

Army of the Dead (2021)

Zack Synder attempted to reinvigorate the zombie genre with the release of his Dawn of the Dead remake in 2004 as his fast-moving zombies were in sharp contrast to the slow-moving Ghouls of George A. Romero’s original film. However, Synder pushed things even further in his spiritual successor Army of the Dead, which separated his zombies into two terrifying categories, Shamblers and Alphas. The Shamblers were more like classic zombies as they were weaker and slow-moving, while the Aphas were highly intelligent, agile, and ruthless. The juxtaposition between these two breeds made the zombies in Army of the Dead scarier.
