The only guided film-location tour I’ve ever taken was a San Francisco Vertigo tour. It was sometime around ’02 or ’03, offered under the auspices of the San Francisco Film Festival. Part of the tour, naturally, was dropping by Scotty Ferguson’s apartment at 900 Lombard Street. The red door was missing but otherwise it half-resembled the original location. No longer — Scotty’s place has since been totally rebuilt and walled off in order to give pesky tourists nothing to see. Go away, we don’t want you around, Vertigo was shot 62 and 1/2 years ago, get a life, etc.
By the way, here’s a 5.9.93 L.A. Times piece I did about Robert Harris and Jim Katz‘s then forthcoming 70mm restoration of Vertigo.
