Actress Tilda Swinton has more archetypal alien characteristics than human ones: extremely wideset eyes, a triangular face, narrow lips, and a pale, androgynous physique. Plus, she has the kind of voice perfect for narrating sci-fi flicks and the kind of stare that makes you feel like she's telepathically whispering into your soul. 

If her appearance isn't convincing enough, we'll refer you to her film Teknolust, in which she recreates versions of herself with her own DNA, one of which we assume is managing @NotTildaSwinton. The Twitter account has amassed over 20,000 followers in just three days. Coincidence or mental manipulation?
