Continuity: A little way into the film, Alex is talking to his mum in bed whilst she is applying lotion to his chickenpox. One moment his shirt is open, the next it is buttoned up and closed, but there was no time for his mum to do it up, it happened in a split second.

Continuity: Alex rings the bell to get his Mom's attention and the box's position changes between shots.

Continuity: After Alex calls the police the first time, his mother herds him into his room. When they first enter there is a shot of his bed, the top pillowcase's open end is first facing right. Then there is a close up of Alex and the open end is facing left. It continues switching to the right whenever the shot is from farther away, to the left when it's a close up of Alex.

Continuity: The pile of clothes that falls onto the remote control car changes between shots.

Continuity: After the trunk of books has fallen on Beaupre and Unger, Unger leans upright and has a blue book on his chest. When it cuts the book is light brown.

Continuity: When Alex gets his remote control car back, he lifts up the viewfinder of the camcorder, then pushes it back down and lays his hand on it. Then he opens the tape compartment of the camcorder, which is empty, and in this closeup the viewfinder is back to pointing upwards. Then in the next wideshot it is pushed back down again and Alexs hand is back on it.

Continuity: When Alex is making his project tip the fishfood into the bowl, between shots the goldfish in the bowl switches sides.

Audio problem: Near the end of the movie when the parrot is going to light the firecrackers, he is talking perfectly even though he has a match in his mouth.

Continuity: When the remote control car that was spying on Beaupre is found, the car goes off and spins on some water in the kitchen, and you can see the laundry basket with a pile of clothes in it. When Beaupre then runs into the room, the pile of clothes is now much different.

Continuity: In the very first scene, a black car pulls up behind the red car. As the car swings round, only one barrel is visible from the long shot. When it cuts to the red car's POV looking towards the car pulling up, there are now two barrels visible, one very close to the red car.

Continuity: Alex's mother goes to make him a sandwich and squeezes jelly onto the bread. The shot comes back after both Alex and his mother talk before she goes out. The jelly has mysteriously been spread.

Continuity: One of the criminals almost gets run over by Alex's mother while running with the dog. As she leans down to say "have a nice day," she places her hand on the roof of the car. The shot turns to Alex's mother, and the criminal's hand can be seen placed on the window, not the roof.

Continuity: In the very first shot of the Mom, she carries in a load of boxes. Two green ones are included, one with writing above the other. When she unstacks them, the shot pans out a little bit, and the boxes are positioned differently.

Continuity: When Alex revs the toy car backward to drag the rug over the stairs into the other room, we can see in one shot the rug only reaches the bottom of the second step, whereas in the next shot of the car coming down the steps, the rug is now further down and you can see that a ramp has been put under it so the car does not fall over.

Revealing: When the criminals are supposed to be in a San Francisco airport, the scene was quite obviously filmed in Chicago's O'Hare airport. They then cleverly catch a flight to Chicago, and then come out at a different part of the O'Hare airport.

Continuity: Alex opens the closet to get his mum's coat, and the big red boxing glove springs out. He then picks up a black pole from the floor in a closeup ... which wasn't there in the previous wideshot.

Continuity: Alex places Doris (in his box) down on the table in the attic. The phone and remote control are neatly placed on the edge. However the shot changes to show Doris placed in between the phone and remote, which have changed places.

Continuity: When one of the criminals confirms her position as "4th house, moving to the alley," the shot moves to Alex running from one window to the other, with nothing in his hands. He goes to push open the window and the shot changes again. Alex now has the car remote control as the window opens.

Continuity: When Unger gets run over by his criminal partner, look at the driver side window. Making initial contact with the car, it is closed. For the close up shot, it's wide open, and when the car turns, it's only open a couple of inches.

Continuity: Alex's Dad hangs up the steamer in the attic, when Alex informs him that his taxi arrives. The metal holder the steamer hangs on changes position with every shot.
