Continuity: Near the beginning, Beaupre and Co. follow a taxi driver to its station and we see it park. It pulls right up to a metal fence. However, when Jurnigen and Unger approach the taxi driver a moment later we can see in the background that the fence is a good distance away from the car.

Continuity: When Mrs. Hess gets off the plane to Chicago, in a wideshot as she places her bags down, her scarf hangs out of the bag, yet in the closeup of her taking out the scarf it is tucked in the bag.

Other: When Jernigan says, "Gotcha." when Alex comes into the room and Jernigan fall, it shows him falling but his expression doesn't seem like he is actually scared.

Continuity: When Alex's Dad arrives home at the end of the film, he hands Alex a remote control car box. Between a wideshot and closeup the box turns around 180° in his Dad's hands.

Continuity: Alex puts the present down to take off his hat and scarf, by the front door. Between shots the present moves a few inches closer to the bag next to it.

Continuity: The main bad guy has Alex cornered in Mrs. Hess' garage. Look at the clear plastic cup behind Alex. One shot the cup is upright, the next it is on its side.

Audio problem: When the police are called for the first time, two officers burst into the house and are confronted by a dog. The alarm strangely stops three seconds after bursting in.

Continuity: In the scene where Alex's mum is about to leave his room after applying lotion to his chest. Alex's hair is slightly scruffy - when the shot comes back to him after being on the mum his hair is combed and neat.

Continuity: When Miss Hess leaves the plane after landing in Chicago, she takes a scarf out of the Parisian bag she has accidentally picked up. Surely she would have noticed the items within the bag were not hers when she put the scarf in the bag?

Continuity: When Mr. Beaupre takes the control car apart, he holds the bottom of the car which has the wheels on it in his left hand, and the top of the car in his right hand. The shot changes and the two parts of the car have swapped over into the other hand instantly.
