“I had my editor count shots. There are 139 dance shots in the film. 111 are Natalie Portman untouched. 28 are her dance double Sarah Lane. If you do the math that’s 80% Natalie Portman. What about duration? The shots that feature the double are wide shots and rarely play for longer than one second. There are two complicated longer dance sequences that we used face replacement. Even so, if we were judging by time over 90% would be Natalie Portman.”
