Scene with Milo & Lisa talking about how they are going to go public with the news about Gary. During the exchange one of the cuts to Milo his eyeglasses move independent of his head. (Milo's head, eyes, brows, don't move but his glasses shift quickly back and worth.) Not as easily seen on a computer but a larger screen it's clearly a mediocre CGI application. Apparently actor (Ryan P) didn't have the glasses on during one of the takes but it wasn't identified until later and it was only a line (one of the cuts from Lisa to Milo where it occurs). I just thought it was ODD when I saw the glasses wobble on their own.
The surveillance recording of Teddy's killing does not match the event as we saw it earlier.
When Milo performs the scratch test at dinner, he quickly pulls his sleeve forward so that Rebecca will not notice. However, when Milo pours the wine for a toast, his sleeve is pushed up. When they raise their glasses for the toast, his sleeve is pulled back to the normal position.
In the daycare center, Phil puts the swinging truck-shaped mouse back on the table in one direction, but in the next scene it is facing the opposite direction.
When Bob comes back to his office where Milo is waiting, Milo asks him if "everything was ok." When he says that, he puts is elbow on the arm of the chair, but when the camera shows him from a different angle, his arm is down and then he puts if back on the arm of the chair as if he had not done that before.
Milo would not have been able to enter the Department of Justice Building without Lyle Barton knowing; the security officials would have informed Barton of Milo's entrance, and Barton would have had to clear Milo.
Although clearly set in Portland, Oregon, Milo and Lisa are shown pumping their own gas, which is against the law in Oregon. However, since they aren't yet on the run, they might be across the river in Vancouver, Washington.
Winston uses IP addresses in the private Class A net 10. This can be accepted as the Internet equivalent of a "555" telephone number. Because of schedule pressure and other plot points, they are indeed likely to be using a largely standard protocol, and not a purely proprietary one.
After Milo returns home from the Justice Department, he goes to the kitchen to make a pot of tea. However, he just holds the teapot near the faucet when he turns on the tap. He doesn't actually add any water to the teapot.
When Milo and Teddy's pictures are being circled in the yearbook, you can see an "email Milo" and "email Teddy" link under their descriptions.
After Teddy is killed, Milo is handed a CD which contains new source code that solves the bandwidth limitations. Unless Gary refactored it considerably, Milo would be able to spot Teddy, and possibly his own coding style instantly. Combined with Gary's comment "its not in the box, its in the band", it makes no sense for Gary to hand Milo such condemning proof.
When Bob has a detective dust for fingerprints on the keyboards in the daycare, he tells him to get the keys that geeks use but kids don't. Any fingerprint expert would easily be able to tell the difference between an adult's fingerprint and that of a child. Any expert would also have found the fingerprints of the spies who used the same computers to steal code from the programmers under surveillance. Given his stated history (former cop) and lack of blind loyalty toward Gary, he would have followed up on those as well.
