10 Great Shapeshifter Horror Movies You May Have Missed

10. Society

As well as providing ample opportunity for scares, shapeshifters are also good for a laugh or two, as seen in this body horror comedy from 1989.

In Brian Yuzna's Society, a man named Bill becomes suspicious of his wealthy family so decides to spy on them. Through a series of startling discoveries, Bill works out that his family and the entirety of their Beverly Hills community are actually aliens disguised as human beings, with a neat, if disturbing party trick. 

The aliens possess an ability called "shunting", which allows them to fuse their gelatinous bodies together into a single, hideous blob. This enormous mass of flesh is then able to absorb victims, draining them of their nutrients and adding to its own power.

To make matters worse, they also don't tip. These rich people are monsters! 

Society is a blatant social commentary about how the wealthy have such different lives from ordinary people that they might as well be an entirely different species. It's good fun, though, and contains some pretty grim scenes of the shunting process.
