Video shows proof Natalie Portman did not dance in Black Swan?

Two months ago, LOOK FX posted a behind-the-scenes look into the production of Black Swan's visual effects. Several clips displayed body double Sarah Lane dancing, as editors superimposed Natalie Portman's face into the shot. Those clips are now missing. Hm...

Natalie Portman

Who shook her tail feather more in Oscar-winning film Black Swan: Natalie Portman or her body double? That's the battle du jour in Hollywood.

Director Benjamin Millepied -- Portman's BF/baby daddy -- says Portman performed 85 percent of the dance scenes.

Body double Sarah Lane claims Millepied is bending the truth. "Can you become a concert pianist in a year and a half, even if you're a movie star?" she scoffed.

Black Swan

Smoking Gun?

But it seems there might be proof to Sarah Lane's claim. Two months ago, LOOK FX posted a video spotlighting how the video crew created Black Swan's stunning visual effects. We distinctly remember a few scenes where they proudly displayed Lane as they superimposed Natalie Portman's face over hers in the dance scenes. Those scenes are now mysteriously missing from the video. Strange? Yes. Solid proof? Not quite.

The online Debate

It appears YouTubers have taken notice of the switch, as well.:

"I remember when this video was at least 4 minutes longer and had the head? replacements," said CarolineEAnd.

"Yes, the original video that was posted (before? whitewashed and coverup) showed five or six face replacements during dancing sequences. This new cleaned up one shows none," says tonyc10011.

The opinions, however, vary.

Some speculate that it's a conspiracy, a last-ditch attempt by producers to save face. Says asu111: "...they pulled that head replacement footage after that video was up for? more than 6 weeks. Why pull it?"

Others think it's inconclusive at best. CapsPLOX shot back: "You base your whole opinion on a reel that had 2 or 3 replacement shots in it. You are using that 4 minute clip as? proof how an entire movie unfolded."

One thing's for sure... someone has some serious 'splainin' to do, though we're not quite sure whom at this point.

What do YOU think? Is the LOOK FX video edit proof Natalie Portman did not perform most of the dance scenes in Black Swan? Or is it all just a bunch of ruffled feathers?
