This office building on the east side of the Main Post of The Presidio is now the San Francisco Film Centre. Scanning the building's directory I notice tenants include for instance Zap Zoetrope-Aubrey Productions, Friday's Films, Actual Films, 72 Productions, Chicken & Egg Pictures, and Edelman Productions, along with law offices, funding organizations, and other services associated with film production.
This seems like a great place for folks in this business to gather since the Letterman Digital Arts Center is a ten-minute walk away on the east side of the Presidio, and the Walt Disney Family Museum faces this building across the parade ground.
I should mention that it's called "The Walt Disney Family Museum" because it was created by Walt's family, not by the Disney Corporation. It is really a museum about Walt Disney as a filmmaker. Not only can you learn about his life and career, you can also learn a lot about filmmaking. He experimented with lots of things that never became family oriented feature films.
So the Presidio is quite a filmmaking hub. No word yet on why they went with "Centre," the European spelling, instead of "Center."
