Behind the Scenes: The Gruesome Secrets of TV's Most Iconic Monsters
How SFX masters create TV’s most disgusting monsters

From the eerie Demogorgon in Stranger Things to the fungal horrors of The Last of Us, television's most terrifying monsters are brought to life through a mix of artistry and downright disgusting techniques. Special effects (SFX) masters have now lifted the lid on their repulsive secrets, revealing how they craft these unforgettable creatures.

The Art of Disgust

Creating believable monsters isn’t just about CGI—it’s about texture, smell, and even sound. Many SFX artists use unconventional materials, from rotting food to animal intestines, to achieve the perfect level of grotesque realism.

From Alien to Earth: The Evolution of SFX

While classics like Alien relied heavily on practical effects, modern shows blend prosthetics with digital enhancements. However, the core principle remains the same: make the audience feel genuine revulsion.

Secrets from the Set

  • Stranger Things: The Demogorgon’s slimy skin was achieved using a mix of gelatin and lubricant.
  • The Last of Us: The Clickers’ fungal growths were sculpted from silicone and painted with layers of decay.
  • Earth: Some creatures were inspired by real-life parasites, magnified to horrifying proportions.

These techniques ensure that viewers aren’t just scared—they’re utterly repulsed.
