Mila Kunis is out promoting her work in the new Mike Judge film Extract, and Collider got her to talk a bit about Black Swan, the Darren Aronofsky film in which she’ll co-star with Natalie Portman. Kunis wouldn’t reveal too much, as she claims the project is under total lock and key, but there are a few choice statements after the jump.

“Yes, it is a go,” Kunis tells the site. “I’m starting production in November and for the past, we started a month ago with the ballet training and I have two more months of training before choreography begins and we start actual production in New York City.” Kunis has been made aware of the online chatter about the film that kicked in last week when a script review surfaced. But she won’t confirm any of the details of that review. “The script is so under lock and key that I can’t imagine anyone really truly ever getting a hold of it…I can’t really deny or confirm because I’m not aloud to talk about the script but all I’m going to say is that I can’t imagine anyone getting their hands on this project. Does that make sense?”

But there is evidently a new draft that could make that script review moot. “I think that Darren Aronofsky who’s directing it is a very…he just did the last rewrite on it and he’s very private about this one rewrite. So I don’t know how anyone could’ve ever gotten it. I have a copy but mine is so watermarked that you would know it came from me. Natalie has a copy and I’m guessing that there are, let’s say, two more out there.” The draft that was reviewed wasn’t Aronofsky’s; it was the previous draft, so at this point anything could have changed.

Kunis is training as a dancer right now, and the film goes before cameras for three months starting in November.
