Here's another one of those videos that takes old black-and-white silent film of some city and someone colorizes it and adds a fake soundtrack. This one's of New York and the caption says it's from the 1940s.
Trying to figure out just when in the forties, I note a movie marquee that seems to be showing the Tom Tyler movie Valley of Hunted Men (1942) and another marquee that seems to be showing the Rita Hayworth film The Loves of Carmen (1948). A possible conclusion would be that we're seeing film from '48 and the Tyler film has been re-released as the bottom half of a double feature. Another possible conclusion is that what we have here is a combination of footage from different years. Take your pick…
