In all fairness, the dancing didn't even come up until Millipied went around saying that Portman did "85%" of the dancing that one sees in the movie. Based on what I gleaned, the reason the stand-in spoke out was because of that and to point out that despite that Aronofsky & Portman implied, one does not dance like that with only 1 year of training-no matter how intense. I don't think it was sour grapes because she wasn't credited.

Also, maybe I saw a longer interview because on E! last night, Portman was gushing how "amazing" her baby-daddy was. I dunno . . . Frankly, it came across as very fake.
