Natalie Portman's fiance has insisted the Oscar-winning star deserves all the credit she has been given for her ballet dancing in Black Swan.
The 29-year-old actress - who met partner Benjamin Millepied making the film and is currently pregnant with their first child - used dancers Kimberly Prosa and Sarah Lane as body doubles for some technical scenes, but Benjamin defended her performance.
He told the Los Angeles Times: "It was so believable, it was fantastic, that beautiful movement quality."
"There are articles now talking about her dance double that are making it sound like [her body double] did a lot of the work, but really, she just did the footwork, and the fouettes, and one diagonal phrase in the studio. Honestly, 85 per cent of that movie is Natalie."
The choreographer said: "[I made] things fluid and not too complicated. By getting more movement going, which in turn added to the camera movement - that is basically what I did. If we had kept things more classical, more restrained, less fluid, it would have been harder to trick the eye."
Natalie, who learned dancing as a child, has talked about the intense dance training she underwent for the film.
Body double Kimberly told The Huffington Post: "She definitely put her work in.
"Just in a couple of months, she looked credible - all the dancers on the set were really impressed at how well she pulled that off - it was pretty amazing."
