The extreme sacrifice behind Black Swan

When Mila Kunis took on the role of Lily in Black Swan, she knew it would be physically demanding. What she didn’t expect was just how far she would have to push herself to transform into a ballerina.

Her preparation involved relentless training, painful injuries, and a strict diet that she later admitted was “very little eating.”

The truth behind a ballerina’s body

Kunis endured grueling preparation for Black Swan, spending up to 12 hours a day in dance training. Her strict routine left little room for rest, with broth serving as her primary source of sustenance.

The toll was immense, leaving her physically drained. Yet the discipline transformed her body into the lean, precise form needed to portray ballerina Lily.

From three months to six, a hidden advantage

Production setbacks doubled the preparation time for Black Swan, extending training from three months to six. The delay came from financing issues, which disrupted the filming schedule but shifted focus back to rehearsal.

For Mila Kunis and Natalie Portman, the extension proved invaluable. The extra months allowed them to strengthen their technique, perfect demanding choreography, and better embody the physicality of their ballerina roles.

When performance pain becomes reality

The demanding choreography of Black Swan pushed Mila Kunis beyond comfort. Hours of rehearsals and repeated lifts left her body aching, with visible bruises marking the toll of the role.

These injuries underscored the contrast between the polished grace seen on screen and the exhausting, physical strain endured behind the scenes, proof of the sacrifices made to bring authenticity to the performance.

A dislocated shoulder and acupuncture to the rescue

Injuries became part of Kunis’s reality on Black Swan. During production, she dislocated her shoulder, a setback that could have derailed her training and performance.

Instead, director Darren Aronofsky turned to alternative care, arranging acupuncture sessions. The treatment proved effective, allowing Kunis to recover and continue the demanding shoot without having to step away from the physically punishing role.

Natalie Portman

The role of Lily began with Portman’s idea

Natalie Portman once revealed how Mila Kunis was cast as Lily in Black Swan. Portman, who played Nina, a ballerina consumed by obsession, said the choice emerged from a simple conversation.

The two had been longtime friends, and during a casual chat, Portman suggested Kunis to director Darren Aronofsky. That offhand remark sparked the idea, ultimately leading Kunis to the pivotal role.

Friendship forged in hardship

Natalie Portman and Mila Kunis had been close friends long before the production of Black Swan, a bond that carried over into the film. Their friendship remained strong despite the film’s storyline casting them as fierce rivals.

Director Darren Aronofsky even tried to stir tension between them, but both actresses laughed it off, maintaining camaraderie throughout the demanding shoot.

Living on broth and discipline

Her minimalist diet was paired with extreme discipline. She revealed that her preparation involved up to 12 hours of dance, training daily, a schedule that pushed her body to its limits.

The intense regimen underscored the real cost of disappearing into a role that demanded both elegance and physical endurance.

“My body was never the same after that film.”

Kunis revealed that losing weight so quickly for Black Swan left her body permanently changed. She explained that when she gained it back, the weight didn’t return to the same places.

The extreme transformation became a lesson. She has also said she wouldn’t look forward to drastic weight loss again, though she has indicated she might consider it for the right role.
