When Neo is in His office sitting at his computer, and the Fed-Ex guy comes

in, look to the bottom left hand corner of the screen, when neo is signing

the paper.. You will see a hand on a green object. I dont know whose hand it

is, but I dont think it was there on purpose, they must not have caught that

one...

Also, When Neo, Trinity, Morphius, Cypher and all the others enter the matrix

for Neo to go see the oracle, and when they come back and Neo has his

"Deja Vu," look at where the cat is standing. It is on a red

carpet. When Apoc or Switch (one of the two, i cant remember) goes down to

see what is wrong, look at the floor again. The carpet is gone, and the

checkered floor is back. I dont know what its supposed to mean, but its

really nifty..

Also, anytime the sunglasses of either Morphius or Agent Smith is being

filmed, look in the reflection. You can sometimes see that the character in

the reflection is not ding what it is supposed to be doing. It is obvious

when Neo and Smith are in the interrogation room. When Neo's mouth has been

"shut" and he stands up and goes to the corner, look in the Agent's

glasses. New is still sitting on the chair in the reflection...

One last thing- When Neo is outside his building, trying to reach the

scaffolding, right before he gives up, around the time were he drops his

phone, when the camera takes a quick shot at the black peice of metal

protrudng out about 2 feet from the wall, the one that Neo hangs on to when

he almost falls, look in the reflection. You can see the outline of the

camera and the camera man. In the first shot it is not quite as clear, but

the second time you can clearly see the camera sitting on the camerman's

shoulder

Ok, maybe another thing... (ive seen the movie way too many times) I know

somebody's mentioned this, but really look and recognize the extra

characters, you can see them later on in the movie if you watch closely..

(the agent training program and the very end, before he flies off, for

example, many people are repeated)
