In the psychological thriller "Black Swan," director Darren Aronofsky used a unique method to enhance the tension between the two lead actresses, Natalie Portman and Mila Kunis. Portman recently revealed that Aronofsky would try to create a competitive environment on set, subtly pitting the actresses against each other. He would keep them separated during filming and send them intimidating text messages about each other's performances that day. However, Kunis has since explained that their pre-existing friendship proved to be too strong for Aronofsky's methods to have much effect. Instead of fostering a sense of rivalry, the actresses would react to each other's successes with supportive congratulations, ultimately making their on-screen chemistry all the more convincing. #shorts #blackswan #didyouknow #moviefacts #moviedetails #natalieportman
