Project Ice Cream, is the supposed name of the movie being filmed in San Francisco. Notices were distributed to businesses in the Financial district saying they will be filming action scenes in the area.
The filming will be taking place mostly on weekends and weekdays from 10pm to 7am in late February. Scenes will include the use of low flying helicopters, pyrotechnics, crash stunts and simulated gunfire!
The fourth Matrix movie was announced earlier this month to be filming in the east bay. Could that be the so called "Project Ice Cream"? A video of Keanu Reeves eating ice cream did go viral a couple weeks ago...
