begin watching at about 1H 45M 15S of the movie (according to the DVD)
- the rooftop battle scene
Neo kick the crap outta some guy (guy A) near the rooftop exit and then Trinity hucks a knife into some poor skull (guy B). Remember where these people fall
Viewer's twelve o'clock - "guy A"
Viewer's two o'clock - "guy B"
after trying to shoot the agent Neo says "trinity help" and here, "guy A" has moved to Neo's one o'clock. Then, when the "money shot" ensues (Neo dodging bullets, the camera does a 360) you can see that "guy B" is no longer there.. must be the windy rooftop? oops, CG people!
"guy A" seems to move a little more to the right again too
