Factual error: When Angela is leaving to go the Mexico, right after the computers are fixed, you can see some guys in US Army uniforms in the background. They have both officer insignias on their lapels, and NCO insignias on their shoulders. You can only be one or the other.

Factual error: Angela Bennett finds the Praetorian's IP while using the PC in the Cathedral's bank: it's 23.75.345.200 - they want us to believe that this is an IP, but no IP can contain numbers greater than 255. [Common practice, like fake phone numbers, but still worth noticing].

Continuity: After Sandra comes out of the shower of the motel, she combs her hair while listening to the news. When she watches the TV it changes from a Sony to a Sharp.

Visible crew/equipment: After Angela has set off the fire alarm at Cathedral & made the others leave, she checks the computer. She hears the fire engines outside, and walks over to the window. As she walks, we can see the camera rig reflected in the cubicle wall glass.

Factual error: Sandra Bullock uses her laptop computer to do word processing but when you see a close-up of the screen the program in use is a spreadsheet.

Factual error: When Angela receives the diskette and calls Dale, he's reading from his monitor that she received the package 3 minutes ago. His screen lists the tracking activity of the package, but only with a time, not a date. Tracking a package without the date would be pretty useless for an international courier like FedEx, which can take days for long trips.

Revealing: When Secretary Bergstrom tells Eddie to, "Take the parkway," they are driving along, yet the transmission is in 'park' and the ignition in the off position.

Factual error: When Angela Bennet comes out of the hospital, the Mexican hotel clerk checks the computer and tells her she's checked out and therefore has no room to sleep in. Although set in Mexico, the message on screen says "Ha salida". This translates to a jibberish "She exit door". The correct translation is "Ha salido". "She exited" or "She left".

Factual error: When Angela goes back to her house and finds that it's being sold, why are the cops letting her busybody neighbor hang around, ask her questions, and give opinions about her answers? If this were to happen for real, I think they'd ask the neighbor if she could identify her and then send her home.

Continuity: In the scene where Angela is entering the computer convention, she pushes past a woman with a curly blonde French twist. In the next shot, the camera zooms out and she pushes past the same woman again.

Revealing: On the beach, after Jack kills the mugger, he "cuts" himself with a knife to appear heroically injured. As the moon glints over the blade, it is obvious that he is pressing the back of the blade into his palm.

Continuity: When Sandra Bullock is looking on the screen at an IP address, we cut from her and the monitor to just the monitor and the IP address changes.

Continuity: When Angela hits Jack with the fire extinguisher the second time, we see it going over the railing with him, but in the next shot of Jack falling it is nowhere to be seen. In the next overhead shot the extinguisher is already on the ground near where Jack is going to land.

Revealing: When Angela knocks the nurse's computer monitor down, there is only a power lead seen, no data lead to connect to the tower.

Continuity: When Angela is confirming her online vacation reservation, the screen shows her Seat Assignment: 8B. Yet a moment later, after she confirms the screen's 8B, it becomes confirmed as 8A.

Revealing: In the scene where Angela is in jail, she goes to make her one phone call. When she is talking on the phone you can see that the receiver is already in the down position, meaning that the call is already disconnected.

Continuity: In the scene where Dr. Champion first meets with Angela in the hotel room, he tosses some folded clothes to her. In the shot where the clothes leave his hands, they are beginning to flip over forward, but when the camera switches to Angela catching them, they land perfectly upright.

Plot hole: When Jack first gets the diskette after arranging the theft of Angela's bag, he cuts his hand to show he struggled with the thief. The next scene shows them on his boat, a few hundred yards from shore, where Angela is helping dress the wound. They then speak of calling the police. When they'd just walked along the beach from the resort, and with the hotel in the background on shore in the scene, why would they take the time & trouble to (presumably go to a dock), get on the boat, drive out a few hundred yards, stop the boat, sit down and THEN deal with the wound, and talk of the police, instead of simply walking back to the hotel & getting it all dealt with immediately?

Continuity: When Dale's plane crashes into the storage silos, we see the cockpit completely explode, yet the next frames show a closeup of Dale just before he hits them.

Continuity: In the scene where Angela trips the fire alarm at Cathedral, and the fake Angela is being prompted to leave the cubicle by some other guy, and she storms out, watch when they switch shots to Angela hiding behind the wall. In the background, you can see the other two in the cubicle repeating the same actions.
