Continuity mistake: The first car he jacks is a white 4 door Oldsmobile Cutlass salon, and a 2 door Olds Cutlass Supreme in the next. (00:09:30)
Continuity mistake: When Marlene buzzes Otto into the office she is holding a telephone, but in the next shot she is holding a pen. (00:12:25)
Continuity mistake: In the opening scene, the motorcycle patrolman asks the driver for the keys to check the trunk. We see him get vaporized and the keys dangling from the trunk, then without getting out of the car, the driver drives away with the keys no longer dangling.
Visible crew/equipment: Just before Otto and Bud enter the liquor store, when the gang (Archie, Duke and Debbi) are leaving having robbed the place, a boom microphone can be seen reflected in the store window's glass near the top (right side of screen). Additionally, when Otto and Bud enter the store, Bud says "awful quiet in here" and the boom mic can be seen again much more clearly in the glass window next to Bud's head. (00:23:45)
Continuity mistake: In the opening scene, after the Malibu is pulled over and the cop approaches from the rear, the person in the driver seat is very short and is not Fox Harris, who is much taller as seen driving throughout the movie.
Audio problem: In the scene where Otto is sitting down looking at the photo of the dead aliens his boss walks out and says keep making me money kid, Otto says something back but his mouth never moves.
Revealing mistake: In the opening scene where the alien car is pulled to the side of the road by the cop you can see two identical sets of tire tracks in the dust in the same place - a sign that this scene was filmed more than once in the same location and the filmmakers didn't wipe away the tracks. As the car pulls out you can see another set of identical tire tracks further up the road as well.
Continuity mistake: When Otto and Kevin are talking about being a fry cook, Kevin's mail is underneath the newspaper. In the next shot it is on top of it. (00:15:40)
Visible crew/equipment: There is a scene in this movie where Emilio Estevez and his partner are sitting in a car outside a shop. The camera tracks in on them. The problem is the crew havent bothered to hide the camera track running from the bottom of the frame up under the car. There is a badly placed black mat that covers a bit of it but this just draws your attention to it.
Revealing mistake: When Lite is shooting back, after Otto tries to repossess the blue clue, his last shot makes the same loud bang but there is no flash. (00:50:20)
Continuity mistake: When Otto meets up with Leila at the United Fruitcake Outlet his face has bruising from a beating that he takes later in the movie. (00:38:15)
Continuity mistake: In the opening scene the car's number plate changes from K88-283 to 127-GBH. (00:03:50)
Continuity mistake: In the opening scene, when the policeman is asking the driver for his keys, the driver is not wearing his glasses. In all other shots he is. (00:03:40)
Revealing mistake: Throughout the film, Agent Rogersz is supposed to have a metal hand however there are many times when you can tell it is just a steel-coloured glove as her fingers move like real human fingers when they should be stiff. The films producers have stated that they could not find a convincing prop in time for shooting.
Revealing mistake: At the end of the film there are a number of shots of the luminous green Chevy Malibu were you can see its license plate is backwards. The shots are flipped.
Visible crew/equipment: When Otto and Lite steal the red sports car at least three baseball cap wearing crew members can be seen reflected in the car's window as Otto winds the window down. (00:31:23)
Visible crew/equipment: When Otto storms out of Bud's car after an argument, we see him walking aimlessly down a straight road. Just before he approaches a red "STOP" sign you can see the boom microphone reflected in the window next to him. (01:05:40)
Audio problem: When the two agents kidnap Leila and drag her into their car you can hear her protesting, however her mouth isn't saying anything. (00:52:18)
Continuity mistake: When Otto is talking to the old lady in her home he finishes the conversation and then puts the tea cup to his lips for a drink. Then cut to a new angle (as the woman's young family members enter her home) and suddenly Otto is holding the tea cup in his lap. (00:42:40)
