Fast forward to about 16m 20s into the movie. Neo is climbing out onto the ledge.
Freeze the action when Neo is just about to grab on to the pillar. Slow mo or frame advance thru the subsequent sequence.
Neo looks down - notice there is traffic on both the street below and the one to the left. (george St)
shot returns to Neo
Neo drops the phone. As the phone drops, notice that there is some sort of parade going on in the street to the left.
shot returns to Neo
Neo looks down again ... the parade has gone !
Also, the phone drops at a completely different time of day compared to the before and after shot -- check out the shadows (explains the disappearing parade I guess)
AND, Why is the traffic on the street below going the wrong way ??? (Note the arrows on the road), yet the traffic on George St is going the right (in Sydney) way ... (perhaps something to do with the parade ?)
