Homeworld

Earth is at war... and we're losing.

The Mendax, an alien race with remarkable mental abilities, are determined to wipe out all mankind. They can pry inside the human mind to trick and confuse us. They can appear human. Infiltration is their art form... 

Basically, if you've ever wondered what it would be like to be completely manipulated by aliens while looking for them in a red-wood forest, than this is a movie you should definitely check out. 

But if afterwards, you feel slightly paranoid or question your beliefs in God- don't say I didn't warn you.
