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].
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.
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. (01:36:05)
Continuity mistake: 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.
Continuity mistake: 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.
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. (00:12:30)
Continuity mistake: 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. (00:10:50)
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".
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? (00:29:00)
Continuity mistake: 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.
Revealing mistake: When Angela knocks the nurse's computer monitor down, there is only a power lead seen, no data lead to connect to the tower.
Revealing mistake: 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 mistake: 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 mistake: After Dr. Champion dies in hospital, Angela pushes the nurse's computer monitor, smashing it on the ground. As she grabs it to throw it down, the front fascia pops off, showing it's just a prop. As well, from the angle we can see the screen, it's black (since it's not really on.). (01:15:15)
Continuity mistake: When a police car is chasing Angela Bennett's car, the wiper blades on Angela's car are moving considerably faster, seen from outside the car, than from inside.
Revealing mistake: When Angela escapes in the dinghy from Jack's yacht, as she rushes to the shore, she smashes the boat into some large rocks. You can tell these are very fake plastic boulders.
Revealing mistake: 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. (00:01:15)
Continuity mistake: When Angela arrives at the Cathedral offices, the elevator she gets off shows "20" on the frame, for the 20th floor, but all other activity references the office being on the 5th floor.
Continuity mistake: In the scene before a police car starts chasing Angela Bennett's car, Highway Patrol is checking her license plate number 3POW893 - reported stolen. But in the very next scene where Angela's BMW is falling from a hill, we can see that the license number of the car is 3POW827. (01:14:55 - 01:15:30)
Continuity mistake: 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. (00:15:30)
