One of the most terrifying elements of The Lord of the Rings trilogy is the chilling, bone-rattling screech of the Nazgûl. These spectral servants of Sauron, also known as the Ringwraiths, are meant to inspire pure dread — and their signature sound played a huge role in achieving that effect. But how exactly did sound designers create these haunting cries? Surprisingly, they turned to an unexpected source: donkeys.
The Unexpected Origins of the Nazgûl’s Screams
Rather than relying on synthesized effects, the film’s sound team opted for a more organic and unsettling approach. They recorded the high-pitched brays of donkeys, known for their naturally eerie vocalizations. These sounds were then distorted, layered, and manipulated to create the infamous Nazgûl screams. The result was a horrifying, otherworldly shriek that sent shivers down the spines of audiences worldwide.
Wings of Doom: Creating the Sound of the Fell Beasts
The Nazgûl’s eerie wails weren’t the only auditory challenge. Their monstrous, dragon-like steeds, known as Fell Beasts, also needed a unique and menacing sound. For this, sound designers turned to something much more mundane — a kitchen grater. By swinging a kitchen grater through the air and amplifying the resulting whooshing sound, they were able to mimic the rhythmic, heavy wing beats of the creatures in flight. Combined with deep, guttural roars, these effects made the Fell Beasts feel convincingly real and terrifying.

The brilliance of The Lord of the Rings lies not just in its stunning visuals, but in its immersive soundscapes. Instead of relying solely on digital effects, the film’s audio team blended real-world sounds with expert manipulation to create something truly unforgettable.
