The best clue to its CGI origins is to look at the interface between the UFO (CGI) and the building (real) it first peeks around from behind. <br /><br />Of course, there is also the fact it was used as a TV commercial by its purchaser, the Sci-Fi Channel. I'm sure the Sci-Fi Channel was delighted that some folks actually bought it and you can count on additional TV ads like that.
