Sarah Lane, Natalie Portman's ballerina double in her Oscar-winning role, stands by her assertion that Portman did not do as much of the dancing as everyone claims.

"They were trying to create this image, this facade, really, that Natalie had done something extraordinary, something that's pretty much impossible," Lane tells 'Good Morning America,' "which is to become a professional ballerina in a year and a half."

As for Darren Aronofsky's explanation that he counted the dance shots and 80 percent of them were Natalie, Lane scoffs.

"It's possible, like I said, if you're counting the close-ups of her face as actual dancing shots. But I don't call close-ups of her face actually dancing," she retorts.
