I can comment on this, actually. Shooting in the real NYC, on a large scale movie, is basically impossible. Asking for permits to shut down major sections of NYC (especially the more noticeable and iconic sections) is absurdly expensive and logistically maddening. And you can't control any elements of the background in a city that densely populated. You might literally spend tens of millions of dollars on a single day's shoot, and bear in mind that a day's shoot usually covers between one and three scenes at most. Tom Cruise bought out Times Square for that one scene in Vanilla Sky, and I think it added well north of $10 million to the production costs of his movie. Now imagine shooting an entire Spiderman movie there, with giant action sequences and what have you. We'd be looking at a $300 to $400 million movie these days. Plus, there are legitimately decent alternatives to NYC that don't sacrifice too much look and feel. The Dark Knight was shot in Chicago, for instance, and I think it turned out just fine.
