Continuity: When Helen is vacuuming the hallway, and goes into Bob's office, the vacuum cord is coming from the far side of the washer and dryer. But when the camera moves inside the office, the cord is coming in the door from the right, which is the opposite direction.

Continuity: When Helen and Vi are talking at the dinner table, Vi's fork changes position a few times between shots.

Continuity: When Lucius is putting aftershave on in front of the mirror, he hears the robot outside and runs to the window, leaving the bottle of aftershave on the desk with the lid off. He returns to open the drawer and the lid is back on.

Continuity: After the dinner table scene, Bob leaves to go out with Frozone. Then Helen turns to talk to Dash. In the first shot, on Dash's plate all the brocoli pieces sit around the steak. Then the shot changes, a brocoli piece is suddenly sitting atop the piece of steak.

Continuity: After Bob gets back home from "re-living the glory days", you can see a barbecue in the back yard and it is on the cement deck. But at the end of the scene, when the camera shows an aerial view of the house, the barbecue is on the grass.

Factual error: When the plane is attacked by missiles, Helen punches a button on the cockpit console and a screen lights up that says "chaff". The next shot shows the rear of the plane with several burning items coming from it that are supposed to be chaff. However, chaff containers burst open into thousands of radar-reflective strips that are meant to confuse radar-guided missiles (see real chaff in the movie Air Force One). What actually comes out are flares that burn extremely hot to confuse heat-seeking missiles. While it might be suggested that we just never see the containers burst open, later in the missile chase we see the exact same items in view for a much longer time and they never burst open.

Deliberate "mistake": During the chase scene at the beginning of the movie, Bob pulls up a map of where he is as opposed to the cop car and the getaway car. The computer then plots a merge pursuit course as being an immediate right, followed by a left turn and two more right turns. The car converts, then is shown taking an immediate left, then a right turn, a mirror image of what the map displays.

Revealing: After Helen finds the hair on Bob's suit, she goes to him while he is in the car and says," Have a great trip. I love you, so much.", Bob backs the car out of the driveway. He backs out and turns, but you can see his hand on the top of the steering wheel doesn't move.
