I need to know what you mean by "fake."
I saw this commercial on television over the weekend. There\'s no reason it couldn\'t have been filmed entirely without digital effects. They just go to a real soccer match, and shoot their streaking scene between the periods or whatever. (they have those, right? damn, I don\'t even know.) The dude is certainly an actor, and so are the cops. They could have easily tackled the guy at the beginning, so they\'re obviously acting.
I was at a Golden State Warriors game in Oakland, where they shot a scene for "Hangin\' with Mr. Cooper" during halftime. No big deal.
