You hear about actors and actresses undergoing heavy training to play characters in action movies, but that's not the only type of physically strenuous role out there. Just ask Mila Kunis, who's preparing for her next role as a ballerina in the movie 'Black Swan.'

"I’ve been studying for the
past month, 7 days a week, 4-5 hours a day of doing ballet cardio and
pilates and I have 2 more months before choreography begins. This
ballet I'm doing you can't fake it," she explained. "Your body has to
be structured differently, your hips have to be turned out, your
shoulders have to be turned in, everything in your body is not natural,
so I'm learning everyday."

Four to five hours a day, seven days a week! Mila must be in amazing shape by now!

Mila will co-star with Natalie Portman in the thriller, and people are already talking about a "racy girl-on-girl" love scene.

"I’m not allowed to talk about the script yet, but I’m excited to work with Natalie. I’ve known her for some time," Kunis said.

So I guess we'll have to wait and see about that part. I have heard they're supposed to be rival ballerinas. A movie that's a thriller about rival ballerinas. It sounds different from all the remakes that are coming out? Are you interested?

You can catch Mila on the big screen this weekend in 'Extract' with Jason Bateman. These photographs are from the premiere.
