While certainly not exhaustive, here is a list of my favorite movies shot (at least in part) in NYC. Most of them are older titles, that is, they were produced prior to 1990. However, there are a few modern titles thrown into the mix (especially if they exhibit interesting art direction, showcase unique city locations or happen to be landmark films).
For any of these titles that have a blog post detailing the filming locations, click on the poster and it will take you to that page. If I haven’t written a post for it yet most of them will take you to a Google photo album of all the before & after pics I’ve assembled so far.
