George Romero’s Night of the Living Dead is a legendary film that redefined the zombie genre in cinema. However, its iconic status came about almost by accident. The director lost out on millions in box office revenue but cemented his place in history.
The film was originally titled Night of the Flesh Eaters, but when the name was changed to Night of the Living Dead, the distributor made a crucial mistake. When releasing new copies, they forgot to include the mandatory copyright notice, effectively placing the film into the public domain.
In simple terms, anyone can use the film however they wish — it can be aired on television, referenced in other movies and series without legal complications, and its full title can be mentioned freely — an extreme rarity in Hollywood.

This bureaucratic oversight resulted in massive financial losses for Romero: despite grossing over $30 million at the box office, he never received the compensation he deserved from numerous home video releases and theatrical re-runs.
As a result, 57 years after its premiere, Night of the Living Dead has been referenced in 129 other films, making it the most quoted horror movie in history. The film laid the foundation for the modern zombie genre, inspiring projects like The Walking Dead and Zombieland, and its influence continues to grow year after year.
