Both Portman and Kunis have admitted that director Darren Aronofsky tried to divide them during the film’s production.

“He’d say, ‘Oh, Mila is doing really well on her stuff.

She’s so much better than you,'” Portman explained.

Aronofsky told the Los Angeles Times that he would keep them apart for much of the production.

Additionally, he’d make them go through ballet training at separate times.

As most real friends do, the women have supported one another through it all.
