Matrix 4 Filming In San Francisco - Keanu Sightings!

Last month we had the very exciting Keanu Reeves sighting in Alameda at Baskin Robbins... well now Matrix 4 filming has begun in earnest in San Francisco, and we have a ton of pics and video.

Any Bay Area Keanu Reeves fan is freaking out right now. First we had these images of Keanu and Carrie-Ann Moss in North Beach and Chinatown.

Now we have this INSANE video of a stunt being performed off the top of a building. Holy crap! No green screen for these folks! This looks scary as hell!
