I was watching an episode of the television show ‘The Saint’ starring Roger Moore that aired in March of 1964, and was set in San Francisco. Although the captures are grainy they’re discernible, and you can see some interesting vintage San Francisco in the images. (Thumbnail images)
You don’t actually see Roger Moore on location in any of the outdoor shots, so his scenes were probably filmed in a studio, but he came back twenty one years later as James Bond in ‘A View to a Kill’. The San Francisco location pictures may also have been stock footage taken in San Francisco from around that time.
Post Street, looking past Union Square to the City of Paris Store: You can’t see the Dewey Monument through the trees from here now.
The obligatory cable car at Powell and California Streets: What’s interesting in this scene is the KSFO Radio Station sign at the Fairmont Hotel, and in the far background, Grace Cathedral before the south spire was built.
Looking down California Street from Powell as the cable car in the previous film picture passes: Visitors got in my way when number 50 passed me heading down California, so I had to wait for the next one, which was number 49.
The southeast corner of Stockton and Post Streets: You see a lot of interesting 50s and 60s cars in these vintage street images.
A scene looking down Geary Street from the northwest corner of Geary and Stockton Streets. Hey, is that lady in the vintage photo talking on a cell phone?

The cars are difficult to recognize this time though. There seems to be a Buick of some sort to the left in the first picture, with a Ford to the right in front of it, but I really do not know.
