“Black Swan” director Darren Aronofsky confessed that he tried to cause tension between Natalie Portman and Mila Kunis during production of the 2010 twisted ballet thriller. The Oscar-nominated filmmaker, 56, spoke about how he attempted to pit the women against each other in an interview with Vogue while celebrating the flick 15 years later.

"My take is that I was trying to be a sneaky director and make them argue," the director told Vogue ahead of the film's 15th anniversary

In 2010, Natalie Portman and Mila Kunis rocked the movie theaters with their psychological ballet thriller, Black Swan. The film won Portman an Oscar for Best Actress, and it’s hard to believe that 15 years have passed since the women stepped into the physically and mentally challenging roles.
