Ever since it was announced, Black Swan has sounded rather strange, and this trailer just deepens the mystery. In Darren Aronofky’s film, Natalie Portman plays Nina, a ballerina whose career seems to be taking off, but who develops a rivalry with fellow dancer, Lily (Mila Kunis). While Nina is the personification of Swan Lake’s White Swan, Lily is more the dark side of the Black Swan. However as this trailer shows, it gets very odd, with weird rashes, bloodhsot eyes, lesbian kisses, and Nina starting to thing Lily is after her. It all looks very allegorical, as Nina gets in touch with her dark side (especially as there’s a hint Lily isn’t real). The film should be in UK cinemas early next year, but click below for the trailer.
