20. Your Rubble Is Missing!
After Agent Smith throws Neo into the wall, when he lands, you can see lots of concrete rubble land on the railway track. However, when we see the tracks again, the rubble is gone!
19. Disappearing Blood 2
For the second time in this scene, Neo's blood goes for a walkabout. Agent Smith has Neo in a headlock and blood is smeared all over is mouth. In the following shot, most of it's gone.
18. Quick Advertising
With films like this, product placements are expected. We already saw Neo using a Nokia phone and in the subway we see an advert for HP Computers appear out of nowhere. Just before Neo jumps out of the way of the oncoming train, there is no graffiti or signage on the wall but when Agent Smith is about to get hit, an advert for HP mysteriously makes an appearance.
17. Olay!
There are many ways to get out of the way of an oncoming train, but the most graceful of all is the cirque du soleil technique of back-flipping, backwards through the air. And just like most acrobats in the circus, Neo is attached to safety wires which can be seen if you look carefully.
16. Awesome Tie!
While Neo elegantly avoids the subway train, Agent Smith is not so lucky, but he does have a magic tie that can sort itself out. As the train approaches, you can see his tie flapping away in front of him and then miraculously, it's neatly pinned with a silver tie pin in the following shot. Wow!
15. Mind The Doors
In the Matrix or not, safety on the underground should be a priority. But after the train hits Agent Smith, you can see that two doors on the train are open. Not only is this dangerous, I cant imagine it being very pleasant for the passengers on the train.
