I went to a screening of Vertigo in 70mm at the Castro recently. Its projectionist came out of retirement specially for the event (which was marvellous!).
That is the most gloriously Old San Francisco thing I've read in months. It must have been an epic experience to watch Scotty and Madeleine roam over the city, in the city, with Bernard Hermann's score. Magnificent.
I got to see it at the Castro a few years ago. There was a fair amount of chuckling at:
"It's a Mission number."
"That's Skid Row, isn't it?"
