Natalie Portman and Mila Kunis
Movie: Black Swan (2010)
What seems like an artsy-fartsy ballet movie becomes much more interesting when protagonist Nina (Portman) indulges in a night of what seems like ecstasy-fueled sex with her rival, Lily (Kunis). But we realize that the lesbian loving was imagined; as the hallucinations continue it becomes clear that Nina is crazy in the coconut. These other visions involve jealousy and suicide; Nina is getting into some dark territory and things will not end well for her. But her fantasy of jumping Lily's bones? If that's a sign of insanity then lock us up with Macaulay Culkin and throw away the key. Now there's a sentence we never thought we'd write.
