Firstly, Mr Cook, HUGE kudos to you an the ENTIRE ImageWorks team. I think it goes without saying that you guys are almost "benchmark" level with regards to the entire end-to-end VFX pipeline.
Secondly, Questions :
1. For the intro fight with Goblin and Spidey, I'm assuming that that was a mix of
a) Live Actors
b) Digital doubles
c) Photographic/Video back plates
d) CG'ed buildings
e) real buildings
Tricky question, but could you tell us what some of the desicion-making process is like for a shot like that ?
I'm thinking its not just the technical considerations, but also time and money budget etc.
2. What were average render times per frame for really complex shots ? I'm just trying to compare to things like Narnia where Aslan scenes took about 9 hours to render!
Thirdly, and i dont mean to contradict what you said, but just suggest a more probable method :

My understanding is that for shots like that, where it appears that time stops and the camera does a "fly around" the subject, what they do is setup an array of cameras (sometimes over 30-40, more ?) in a ring around the subject.
Then, they fire the cameras off all at the same time
(say, when a person jumps up and reaches the height of the jump)
The result is that you have multiple frames of the subject from different angles, but at the same time
. So, you just play those frames back in sequence and it appears that a single camera is moving around the subject in freeze-frame.
Hope that answers your question, akhenaten.
And thanks again for taking the time out of your obviously crazy schedule to answer our questions, Mr Cook.
