London: Mila Kunis who played tempestuous Lily in `Black Swan` says she starved for much of the movie shoot to fit into the shoes of a ballerina.
The Russian-born actress had to appear superslim in the ballet thriller and watch her calorie intake at all times.
She shed 20 pounds (9kgs) and weighed in at just 95 pounds (43 kgs) by the time the film wrapped.
But Kunis, who earned critical praise for her spirited performance says would not hesitate in losing weight again if she is offered a role like that.
"I was on a five meal-a-day diet of 1,200 calories. I could eat anything that fit into the palm of my hand. That`s it. It was hell but I wouldn`t trade it for the world... How often can you lose 20 pounds, get en pointe and work with brilliant people."
