10 Scariest Horror Movie Scenes From The '80s

10. The Transformation - An American Werewolf In London

With An American Werewolf in London, director John Landis successfully blends horror and comedy, a task that many have failed to do. After all, lean too hard in one direction, and the whole movie falls apart.

While the humor here is great in this entry, it's the horror that lands it on this list. In particular, the innovative body horror.

The transformation scene, in which David violently metamorphoses into a werewolf, is gross in all the best ways. Achieved entirely through practical effects, it is impressive just how convincing each body contortion is. It all feels so real.

The practical effects aren't the only the reason the transformation is so horrifying, the striking use of sound is also wince-inducing. The sounds of David screaming and his bones cracking and morphing into shape are haunting. They effectively sell the pain that a transformation such as this would cause.

It's an impressive scene, but one that is extremely difficult to watch.
