Continuity mistake: In the scene where Roger and Hoskins are moments away from crashing into a bridge in the cab quickly look at the road there is no gate in between the roads. But when they jump onto the bridge they crash right into a gate. (00:57:15)
Visible crew/equipment: When Drebin chases the doctor out of the hospital, the doctor gets a car, while in the background, Drebin falls from the ladder. Drebin then emerges from under the car. The doctor drives off, and Drebin enters the foreground. Look in the windscreen of the car Drebin emerged from. The top of a man's head with grey hair appears at the end of the shot, thinking it's over. This is the stunt double that dropped from the ladder. (00:32:25)
Continuity mistake: In the basement of the Orpheum theater, Holmes takes a lamp off of a wall and places it on the floor. The shot cuts, and the lamp is back on the wall. When the shot cuts again, the lamp is back on the floor. (01:29:25 - 01:30:45)
Continuity mistake: When Garfield is in outer space asking the computer to tell him if he's really living in life number 9, his armchair vanishes for an entire shot. (00:40:00)
Continuity mistake: When Delia spray paints the word “mauve” on the wall, between shots it is apparent that the script of the word changes. One example would be that in the first shot the tops of the letter “M” are pointed, like triangle tips, but in the next they are more rounder. The writing also moves lower on the wall. (00:15:50)
Continuity mistake: When Sykes is at his desk monitoring Fagin from a security camera feed, Dodger suddenly appears onscreen between shots, right beside Fagin. (00:51:00)
Continuity mistake: John Heard's racquet jumps from one hand to the other when he and Tom Hanks fight on the tennis court. (01:17:20)
Continuity mistake: Throughout the film Elvira wears her trademark black dress, split to the top of her thigh, and underneath it she always wears black pantyhose. Inexplicably, this changes to black stockings and suspenders when she is undressing for bed on her first night in her new house. (00:31:35)
Visible crew/equipment: When they're building the petticoat balloon, the camera slowly goes back. Look at the lower-right corner of the screen: there is a man wearing a stadium jacket. He's a crew member.
Continuity mistake: When General Kael takes the baby to Nockmaar Castle, it has an extra 'turret' on the left-hand side, which has disappeared when Willow and Fin Raziel face the castle later on. (01:31:40 - 01:41:15)
Revealing mistake: When Otto is firing at Ken, while Ken is driving the steam roller, you can see the explosive pack on the steel post before the bullet hits it. (01:38:05)
Continuity mistake: Arnie enters the parking lot driving on two wheels crying "Woooa." The close shots show him with one hand on the wheel and the other outside on the window; but on the wide shots, with the stunt, both hands are inside and his mouth closed but still the cry is heard. This mistake goes on every time angle changes.
Continuity mistake: The ruler in Tess' hands instantly changes design. It looks like she flipped it over between shots, but without any time or reason to do so. (00:19:20)
Continuity mistake: In the scene where Bill's old boss comes back to see him notice when Bill shoots him and takes the drink. All of the drink comes out of his chest because of the bullet holes. Well notice his shirt is all wet, then in the next scene when he takes off his hat his chest is all dry.
Continuity mistake: The 3 girls lock Sadie Shelton in a closet and then bring a chair to secure the door and Rose sits. A couple of seconds later, Rose is standing again holding the door. (01:28:05)
