Mark Ruffalo outside my window

I walked across the street to the store awhile ago and noticed on-coming traffic. Then I noticed the cars were not moving on this otherwise busy thoroughfare. Then I realized they were all cars from the 60's. Then I notice the SFPD, the movie crew...then I spot the actor Mark Ruffalo.

They are making the new Zodiac killer "Chronicles" movie in my hood! Cool
(the movie, not the killer).
