The Aliens (Circle)

The Aliens are the unseen main antagonists along with Eric in the 2015 horror movie Circle.

Biography
Nothing is known for certain about the aliens, where they are from, what they look like, or how many of them came to Earth. The only thing known of them is that they have the ability to use tractor beams to kidnap 50 humans at random per ship and keep them asleep for as long as they want them to be with alien drugs.

Description
The aliens themselves are never seen throughout the movie, only their ships at the very end. One of the kidnapped people aboard the sip, Howard, says that he saw them personally before they all woke up in the room they're all in, saying they he woke up in a red room with several unconcious people piled on top of each other just like Eric mentioned and that they looked "big and black, dark green maybe. And wet". He also said they spoke in a language that sounded Chinese.

However, given that his credited name is also "Old Man Liar" and he could've been lying to protect himself along with the other elderly people, it's most likely none of what he said was true.
