San Franciscans, and particularly those living in the Castro neighborhood, are not happy. The comments after the article reflect that pretty strongly. I can't blame their trepidation and disappointment. While I love what Another Planet has done in turning the Fox in a vibrant music venue, that project developed from scratch at the point the theater was restored via private and government funds after being shuttered for two decades and nearly demolished on a few occasions. The Castro is a different story, with so many popular traditional events over the course of the year that are now in jeopardy. To wit, a spectacular new pipe organ was installed there last year, and one wonders what will happen with that. As for Noir City's future in the Bay Area's premier city, who knows? There simply aren't many vintage theater venues remaining, so the Grand Lake -- bastardized with an ugly cement wall in the 1980s to turn the the balcony a second theater -- may have to do. Berkeley's University Theater, which also used to be a specialized film haven, has also become a live music venue.
One more reason the Noir City event may have moved to the Grand Lake in Oakland: The venerable Castro is getting a facelift and may cease to operate as a movie theater under a new arrangement with Another Planet Entertainment. The linked story does indicate there may still be some film events at the Castro, but if APE's transformation and stewardship of the Oakland Fox is any indication -- films are no longer shown there at all -- future week-long film festivals wouldn't appear to be very promising at the Castro.
