the running scenes look a little too real,, all generated ?
Yes, all cgi. The term escapes me at the moment, but they probably used a digitized, live-action reference film. The actor wears a black skin-tight body suit with reflective balls located at certain points on the human frame. Those balls, as the figure moves, are scanned into a computer which can duplicate those movements so the cgi animation will appear more fluid and human-like.
The man responsible for this ad is Neill Blomkamp / The Embassy.
I've not spoken to him in a couple years so I'm not sure what he's up to. But I'm sure it's something groundbreaking in the area of 3D animation and/or film direction. Real nice guy, and incredibly talented. He was based here in Vancouver last I heard.
Do a search under his name or The Embassy FX to see more of his work.
An old high school buddy of mine made a fun short with him once. Kind of a take off on the Kung Fu fighting/Matrix movies. All very tongue in cheek and very fun.
