Marvel movie fans know that Ant-Man is filming in San Francisco for a 2015 release. The last few evenings Buena Vista West has been closed to through traffic because Michael Douglas and others have been filming on tiny Java Street.
And if you are in the neighborhood, notice the large condo building across from Buena Vista Park near Park Hill. It used to be a hospital and was used for one if the exteriors for Vertigo (where Scotty/Jimmy Stewart was in convalescence).
Seems like a lot of filming going on in the city these days. We were in a bit of a lull for awhile.
