yes you are right brian. in part 1 the scenes that got help of cg was very obvios not real film. in part 2 there were probably not many scenes at all that did not include some sort of cg.

if i come to think about it - in part 2 there were not too many (if any) compositing errors visible. they must have done a good job hiding all the computer stuff. and the transition of real neo to cg-neo was great - wow. at least i believe there was sometimes a cg neo - but i could be wrong - maybe only his clothes were cg.
