Although Natalie Portman and Mila Kunis had a cutthroat rivalry in Black Swan, life did not imitate art for the actresses.

“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.
