“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.

Mila Kunis knows what you’re not supposed to say about preparing for a movie, but she’s going to say it anyway. The actor opened up to Vogue magazine about the intense time she spent training for the Darren Aronofsky film, “Black Swan,” for a retrospective piece in honor of the 15th anniversary of the movie.
