What's the Name of Your Movie. Mission Film Shoot?

SFist Jonathan sent us this image of some sort of movie shoot happening in the Mission today. He explains, "There's a huge film shoot setting up on Valencia between 20th and 21st -- like 6 trucks, 2 motor homes, huge generators, scads of crews running around." Glamorous!

Since we're scared of the Mission because it's riddled with crime and trustfund vegans, we couldn't tell you, dear readers, what's going on. But maybe you know?

Update: It's not a movie. It might be . Mayor's office confirms that it's for a commercial. "Maybe for Comcast or something," we're told.
