I just started watching this, and all I have to say to my drunken scot friend is this:
Try modelling & texture-mapping any one of the elements in that film. Then set up the bones & joint / IK constraints on them. Then keyframe animate it, then set up the dynamics/collisions. Then light it, direct it, film it. At the end, you would have a boxy piece of crap. Not only are these guys talented artists, but you have to be borderline obsessive genius.
