Sarah Lane, who was Natalie Portman's dance double in "Black Swan," says the producers are lying about how much Natalie danced in the movie. She says producers told her to keep quiet about how much she actually danced in the film, but now she's speaking out. Lane says she doesn't want to ruin Portman and thinks she's a great actress. She claims she just wants to let people know that it takes a really long time to learn how to dance. Perhaps Sarah wants some publicity? Maybe she's upset Natalie didn't thank her in the acceptance speech? Sara explains herself in an interview she did with ABC.
