Continuity mistake: When Frank is at the party when the queen arrives, before the horns blow in his ears he's about 1 foot away from them, but the close up of him shows his ears even with the end of the horns. (00:56:50)
Continuity mistake: When Frank does his speech at the end, his chest protecter goes from being wrinkled and squished in one shot, to perfect condition in another, and then back to wrinkled again in the next. (01:17:30)
Continuity mistake: When Ludwig demonstrates the hypnosis effect with his secretary, she drops her revolver near the door. When Ludwig picks it up, it's several feet away, near his desk.
Continuity mistake: When Ed and Frank drive up to the Police Station, they are towing a luggage trailer that Frank backed into at the airport that didn't have any signage on it, but now sports a "DynAir" placard.
Continuity mistake: When Nordberg is at the I Luv You, the "u" in "You" is partially faded. When Nordberg's wife hands Frank the photo of the ship, the letter is fully visible.
Continuity mistake: At the end of the movie, when Jane is under control, she points the gun at Frank. The shot behind Jane, she has both hands on the gun. It is tough to see, but it is happening. The camera changes to show Jane, and her left arm is completely down at her side.
Continuity mistake: When Frank hits the garbage cans in his car, causing the airbag to go off, watch how they are inflated during this sequence. The airbags are deflating in the oncoming angle but then are sticking out of the passenger window in the opposite angle.
Continuity mistake: When Frank's plane is landing, it's a DC-10, but when Frank is getting off the plane, it's an L-1011.
Continuity mistake: The aircraft landing at the beginning of movie is a United DC 10. The aircraft taxiing to the parking area is an L1011.
Suggested correction: This has already been addressed earlier. There is nothing to suggest the 2 jets are related in any way. They just show a jet landing and a jet taxiing.
Continuity mistake: While there is a "grand slam" depicted as one of the jokes, the inning-by-inning scoreboard never shows the Angels scoring 4 runs in an inning.
Continuity mistake: When Frank is chasing the doctor who tries to kill Nordberg, the doctor crashes into the missile and you can see Frank's vehicle behind him as it should be. Right before the fireworks scene, Frank's vehicle disappears. It should still be following the doctor.
Continuity mistake: When Drebin first meets Ludwig, you see the shelf of vases. To the left of that is the fancy painting. However, when Drebin accidentally sets fire to the office, he rushes to the shelf to catch the vases as they fall. He then look to his right to see the flames getting close to the painting. He moves to his right (pulling down the shelf of vases in the process), takes the painting off the wall, and impales it on the plant. It should've been the other way around. Drebin should've looked and moved to his left instead of his right.
Continuity mistake: As Reggie Jackson starts walking toward the Queen at the end, the scoreboard behind him no longer shows three outs as it did moments before.
Continuity mistake: After deactivating the hypnosis, Ludwig has the remote in his left hand. A second later, it's in his right hand.
Continuity mistake: During the press conference, Frank has one empty pitcher in front of him, and is draining a second one. The third full one is positioned on the next tray. A moment later, the full one is suddenly in front of him.
Continuity mistake: Just before Frank accidentally nudges one of the fishermen into the river with his car, if you look in the background there is a police car. In the next shot of Frank getting out of his car on the pier, the police car is now noticeably much closer than in the previous shot.
