Hi,
couldn't you create almost the same film by panning over still images?
Best,

Won't answer for Chris but I tried this tech several times and it's not the same at all.
You can check in the movie the backgrounds, they move in "3D" with the camera. Nothing that is not exactly paralell to the plan would appear totally flat and unrealistic using stills and panning.
There are parts of the footage where you could apply that successfully (when zooming details without changing the viewpoint
AND with nothing happening in background) and others that won't work and you need to film, so the logic is filming all.
Long travelings just do not work with stills. You can check in the movie that the perspective is following the motion and always does with any movement: for ex
check from 059sec to 1.07 and watch the table feet carefully. You see the perspective changing following the traveling because the eye point is changing. With a still, the table feet would stay at the same angle wich results totally unrealistic, flat and artificial.
From 1.26 to the end, the need of motion capture and not still is even more clear. See how the perspective is following the camera movement. That beautifull movement, the space involved and how elements combine in "3D" space requires the motion medium.
Even if video is 2D, you want the sensation of real space while moving and that affects the eye viewpoint, so the perspectives. Stills are unable to produce that effect.
