The camera is on a track, which was my first clue this wasn't just a local news production. They are filming outside of the Federal Building (not my building, I am across the street), and a lot of people come into work late (typical Federal employee) so there are a lot of people crossing the street into their shot... which leads me to believe that they are filming a "coming into work" commercial (or scene for a movie).
I don't think this is HBO.
UPDATE: I am pretty sure it is going to be a car commercial -- they have hosed down the streets --- but it is not that nice of a car (tan Camry) and the windows aren't tinted and the license plate is on the vehicle (unlike car commercials).
UPDATE: It is confirmed that it is a commercial starring former 49ers quarterback Steve Young.
