I’ve seen that film. Amazing what changes and what doesn’t in 65-ish years.Couple of things:
There's a really stupid movie from 1958 called The Line-Up, based upon a TV series that aired in the 1950s on CBS and in syndication (the syndicated episodes were titled San Francisco Beat). The plot is dumb and the acting doesn't do anything to save it. It has one redeeming virtue: it was filmed in San Francisco. The scenery alone is worth it, even in black-and-white. The movie ends in a chase on the ramps south of Market leading the Embarcadero Freeway, then still under construction. The dramatic tension comes when the chase-ee runs out of ramp and has to stop with nowhere to go. From having worked in the area for about 20 years, my guesstimate is that those ramps were around Main & Folsom, near or even on the lot that was used as the temporary Transbay Terminal when the new one was being built in the 2010s.
The other thing - if you like Paris, I think you'll love Lyon. An amazing setting, great food, and people are very welcoming.
We drove through Lyon on our way to Nice in 2022. I’m sure we’ll actually spend some time there soon.
