Like I commented on YouTube, this adds a three dimensional depth to the shot. Before, it was just a flat zoom in on the gantry, but now, it's an actual camera push in on it. One of my gripes with the prequel cinematography is all the zoom ins. I get George was going for an old 30s or 40s style, but no cinematographer would recommend doing that kind of thing. While I have done the zoom in thing when I've been shooting my own films, it's only because I don't have a dolly track to do ths kind of camera move. This demonstrates the added depth of field and quality of a push in over a zoom.
