An allegation by Sarah Lane, a soloist with the American Ballet Theatre who worked on the filming of 'Black Swan' as Natalie Portman's dance double, has prompted Fox Searchlight to issue a statement about the controversy.

Lane recently claimed her body is what moviegoers see in most of the film's ballet sequences, and she estimated that Portman did about "5 percent" of the dancing seen in the acclaimed drama. The lifelong ballerina has scoffed at the idea that an actress could train for just a year and achieve the level of expertise Portman's character exhibits on screen.

The filmmakers couldn't disagree more, insisting that Portman, who won an Oscar last month for her demanding role, deserves most of the credit for the performance.

"We were fortunate to have Sarah there to cover the more complicated dance sequences and we have nothing but praise for the hard work she did," the studio said, according to EW.com. "However, Natalie herself did most of the dancing featured in the final film."
