10 Horror Monster Movies With Amazing Special Effects

10. Society

In Brian Yuzna's Society, teenager Bill suspects his high-class family are hiding a dark secret from him. 

During the climax, Bill walks into his house to discover his family and friends aren't human. Just when it seems like things couldn't get worse, he finds them engaged in a "shunting party" where they merge their bodies into an amorphous blob for orgasmic pleasure.

Up until this point, only minor effects and camera tricks have been used to indicate Bill's family aren't what they seem. However, the last 15 minutes is a truly unnerving feast for the eyes, as Billy is tormented and taunted by all sorts of surreal beings (including the infamous butt-head). 

It's a simple touch, but the squelching sounds and the participants' oily textures really sell the idea these creatures are living organisms, rather than rubber puppets. The red lighting blaring throughout this cerebral sequence helps to depict the shunters as hellish and nightmarish creatures, magnifying their unsettling nature.

Society's pacing may be slow, but it's worth sticking with, since the ending is an absolute wonder to behold, especially for SFX purists.
