4The Amusement Park

Amusement parks are supposed to be fun, family-friendly vacation destinations where dreams come true. However, the amusement park in George Romero’sThe Amusement Parkis a little different. According toABC News,the film was originally commissioned by the Lutheran Service Society and was supposed to be an hour-long educational film following the plight of the elderly. However, Romero stepped in and made the film his own, thus, failing to impress the Lutherans.

Monkey Shines

The final product feels part documentary and part home video, a home video from hell that is, which follows an elderly man having a horrible day in a seemingly “normal” amusement park.Considered a ‘lost movie’for decades, Shudder found and restored it, bringing the world an early experiment from one of the world’s greatest filmmakers.

3Land of the Dead

“The world as we know it is no more. The land of the living has become the land of the dead.” The fourth film in George Romero’s legendary undead franchise, 20 years afterDay of the Dead,Land of the Deadfollows a group of human survivors who have formed an outpost safe zone in the city of Pittsburgh, Pennsylvania. However, the dead never rest, and eventually, they discover this sanctuary city with one mission in mind: to kill and feast. Romero ups the sociopolitical commentary of his earlier films and creates a wicked, nasty political satire.

2Day of the Dead

It’s everybody’s “favorite” day, the day of the dead! In George Romero’sDay of the Dead,the zombie apocalypse has ravaged the entire planet and the undead have infected everyone they can get their hands, or teeth, on. Now it’s up to a small team of scientists, civilians, and soldiers to save the day, or rather, the humans from becoming zombie food. TheDay of the Deadis the third film in what was supposed to just be George Romero’s undead trilogy, coming afterNight of the Living DeadandDawn of the Dead.The film is a harsh critique of the military-industrial complex, and 35 years later was turned into acreepy TV series on Syfy.

1Night of the Living Dead

“Welcome to a night of total terror,”where the dead won’t stay dead! InNight of the Living Dead,the dead have come back to haunt and feast on the living and the living are trying their best to stay alive. It’s a classic battle of good over evil, the living versus the dead. The first film in a trilogy is often the best and that’s whyNight of the Living Deadclaims the number one place on this list. A favorite among both film critics and moviegoers, this horror classic remains one of George Romero’s most beloved masterpieces, even over 50 years later.
