Aronofsky states that the film would never have got off the ground without Portman's enthusiasm and dedication. • Aronofsky would subtly try to pitch Kunis and Portman against each other such as keeping them apart off-screen and texting one actress to tell them how good a performance the other gave. It didn't work - Kunis and Portman were already good friends so they congratulated each other instead! • Portman met her future husband Benjamin Millipied on set. Millipied not only played the role of The Prince during the film's production of Swan Lake but also choreographed the film's many dance scenes. Rarely have I encountered a film that was so different to how I expected it.
