share: digg facebook twitter Natalie Portman is staying mum about her Black Swan dance double's claims that she only did a small portion of the dancing in her Oscar-winning performance. Last month, American Ballet Theatre soloist Sarah Lane told Entertainment Weekly that Portman performed approximately 5 percent of the dance scenes in the film, while she did the rest. Lane added that the film's producer, Ari Handel, asked her not to discuss her work with the press because the producers wanted to play up Portman's training and dancing for her Oscar campaign. Natalie Portman did "every ounce of every one of her dances" in Black Swan Among Lane's complaints is that the actress did not thank her in her Oscar acceptance speech, but Portman says that she doesn't "remember my Oscar speech at all, and I'm actually too embarrassed to watch it."
