I drank a lot of broth and danced for 12 hours a day." Vanity Fair / Via youtube.com The actor, who stands 5'4," previously revealed that she got down to just 95 pounds so she would "look skinny" enough to convincingly play a ballerina. "Because I'm not a ballerina, I have to get on point within three months, and so to get on point, you almost have to fake it," she told Howard Stern in 2016. "So, the best way to fake it is to unfortunately look like it." (C)Fox Searchlight/Courtesy Everett Collection "I smoked a lot of cigarettes and I ate a limited amount of calories," Mila added, specifying that she survived on an average of 1,200 calories a day. She told Howard that she had since stopped smoking, and although she insisted she lost the weight "in the healthiest way possible," she said she wouldn't recommend her regimen to anyone. "I don't advocate this at all," she stated. "It was awful." SiriusXM / Via youtube.com In the Vogue interview, Mila also opened up about other challenges while filming, including the physical toll that dancing eventually took on her body.

I also dislocated my shoulder pretty early in the production and thought I was completely screwed, but [director] Darren [Aronofsky] sent me to an acupuncturist and I somehow came out totally fine." Eric Charbonneau / Getty Images According to her, Natalie also suffered an injury on set while shooting the scene of Lily being pushed into a mirror. Natalie told Vogue she "completely blacked that out" and did not have "a hint of a memory" of it, but Mila recalled, "You were scarred up all around your neck."
