Let's see. We have:
1. Natalie Portman being intense and driven but also (gasp!) vulnerable. Check!
2. Vincent Cassel being sinister and manipulative. Check!
3. Natalie Portman and Mila Kunis getting all up close and personal. Check?
I am so sure that all kinds of things that are not at all predictable are going to happen and it's actually so mind-blowing and not merely an excuse to have two nice-looking actresses wear not-very-much and make not-actual-porn. This is definitely true. No one is type-cast at all. It's very deep. Says many important things about perfection.
Oh, and then Natalie Portman grows feathers. Awesome.
PS: No, I have not seen it, and I am not going to. I hate both Natalie Portman and pretentious films.
