so we really weren't able to shoot anything on location in new york. we sent a small team there and they did some photographic reference, they had a couple of days in a helicopter where they shot some aerial footage for us, but the majority of the actual plate photography, with the real actors, was done in atlanta on a stage there. so they built like a 200 foot long piece of highway with real cars and that's where too holland and alfred molina were physically there fighting each other. we did have to then fill in the entire environment around that because it's a very small set. for the most part, tom was in his iron spider suit, so he's all cg, doctor oct has these big giant cg arms. and when they're fighting he's cg. and if they're throwing around cars or doing anything crazy, sometimes the entire frame is cg. so what we had to do was start with a scan and a lot of photographic reference of that environment and then, from that, build just a very accurate photo real representation of about three square miles of new york.
