Where Ro is eating her Ben and Jerry's ice cream, the container is turned in several different motions and the amount at the top is different each time although her hands stay the same
When Ro is arguing with Cam the back of her dress is unzipped. When they finish arguing and he walks away, it shows her back and her dress has been zipped up.
When Miles is talking to Rowena on the phone, after she sent him the secret laptop audio transmission of Senator Sachs, a woman with long hair and eye glasses walks past his desk from the far left of the screen. When Miles stands up, the same woman goes past his desk, again from the far left.
AS Rowena is dressing to go out, she selects and dons frilly black thong panties. In the next shot, as she bends over to pick up her shoes from the closet, the outline of full-bottom briefs can be plainly seen through her dress.
When hill goes to hit Ro you see from the front that his fist is clenched, but when you see him from the back its unclenched.
Just as the phone numbers said and shown in movies are almost always fake and non-existent(so that real people do not receive calls from moviegoers making the movie itself a liability)- so are the 'IP addresses' shown - Miles is hacking into Harrison's "blade server", and a list of IP addresses appears on the screen. The addresses are incorrect. An IPv4 address consists of 4 numbers separated by dots. Each of those numbers can be 0-255. But most of the IP addresses shown on the monitor have at least one number over 255.
Not to pick on this particular movie but more to just put up a little flag because it happens often in films about, or featuring, reporters: the prestigious award mentioned is not, and has never been, called a PYOO-lit-zer--it is called a PULL-it-zer. No editor, reporter or professional writer would ever make this mistake.
Miles is supposedly searching Harrison's files for a picture of someone named "Veronica". Two screens of information are shown to illustrate this. The screens have nothing to do with searching for a file. The first is a screen of "fdisk", a Linux program for formatting partitions. The second looks like an FTP log, which appeared earlier in the film as well.
Outside the bar, a taxi drives right by Halle Berry into the intersection. When seen from above, STOP is stenciled in the street before the crosswalk, yet there is no STOP sign evident on the corner which is required by the Manual for Uniform Traffic Control Devices (MUTCD) to make the taxi stop there.
When Halle is entering the Senate building, DC police are manning the security checkpoint. In actuality, the US Capitol Police would man the checkpoint.
It would be impossible for Rowena to "transmit" the conversation with Senator Sachs to NY due to the fact that Rowena did not have an internet cable plugged into her computer and would not have access to a wireless connection in the senate building.
When Hill and Roe are having dinner, Roe goes to the restroom. Hill answers Roe's phone to read the text message, but the phone is on silent, so how did he know she had received a message?
After Ro and Hill leave the restaurant, when Hill is going to confront Ro with the text message he read on her phone, the car they get into has twin-spoke rims with 7 spokes. The car that stops under the bridge have rims with 10 thin spokes.
At 35:23 the band stops playing to allow Harrison to make a toast. In the background, as Harrison is already standing up to walk to the stage, some people continue dancing even while the music has stopped.
If Ro is using a fake name to hide her identity at H2A, how did Hill find out where she lives, and give her a ride to work?
When Hill confronts Ro in the car after their dinner, Hill raises his fist as if to hit Ro. In one part of this scene (1:16:40 DVD) you can clearly see the boom mic reflecting in the passenger door window behind Ro.
