I know,they"retouch"the camera-crews out of the shot.You can see it at 0:32 Ariadne"s left foot is step on the white line, BUT look carefully in the 3rd leyer of reflection,her lef foot did NOT event step on the line yet (for more detail-on HD),because CGI people has to remove the camera reflection, replace Ariadne"s reflection back(because that"s where camera at), there for it"s not lined up like real action.And yet they have to remove it in every reflections, I know because I did that before.
