I love this "now and then" essay about the locations used in the movie "Annie Hall": The Filming Locations of Annie Hall, Part 1 – New York, You’ve Changed.
Annie Hall is one of those few Woody Allen movies that I actually sort-of "got", so I remember it quite well.
It's interesting that some areas have dramatically changed in 36 years, others not at all.
We've noticed the same thing in our neighborhood, though we've only been here 24 years. Some areas are completely un-recognizable from how they were a quarter century ago, while others haven't changed a bit.
