You can't tell much from this picture, but across from the yellow taxi is a movie scene. See the broken-up concrete and the dusty car? It's all fake. I think there were more people working for the film company to keep people away than there were doing anything else. Do you think all those people waving New Yorkers away from the scene and telling them to hurry along, get out of the way, etc. get credited at the end of the film?
