Revealing: When Ace and Melissa are in bed together having sex if you look close enough you can see that she is wearing underwear.

Continuity: When Ace rescues the dog and replaces it with a toy-dog, the toy-dog is in an impossible position. Ace had to place it there when the door was still open, but if door was closed after that the man should have knocked over the dog.

Audio problem: At the beginning, when they steal the dolphin, you hear the peel-out sound effect as if the truck was on a paved road, but they were on grass.

Revealing: At the end of the movie, when Ace is at the stadium and he attacks the mascot, his name is called and he looks up to smile and wave. He is surrounded by players from the Miami dolphins, but if you look through the crowd of players you can see the stadium seats are empty.

Continuity: When he is in the asylum, he is trying to hide in a little cardboard box from an employee of the building, so he crams himself into a box and when the man leaves he breaks out of it. He ends up completely squishing the box underneath him. When the camera comes in for the close up shot, the farthest side of the box from the viewer is now undamaged.

Continuity: When Ace is trying to work out what Irnhorn and Finkle have to do with each other, his dog sits on a photo of Finkle and its hair does not cover the face, the shot moves to Ace and then back to the dog and now its hair is covering the face of the photo without even moving.

Continuity: When Mr. Shikadance looks around Ace's apartment the dog door on the fridge is one piece. Later, when the penguins come out it has five strips making it easier for the penguins. The rug moves closer to the fridge too.

Continuity: When Ace is sneaking into Ronald Camp's Private Aquarium, he begins to look around and open some doors. If you look at the colour of the wall it is red. When he opens the door to the giant tank, the wall outside the door (which should be red) is now white. The door also reverses - the handle goes from Ace's left to Ace's right.

Continuity: In the beginning when Ace is "delivering" the package he walks into an elevator and the doors quickly close on the box, but when nothing is blocking the doors, they close much slower than the first time.

Continuity: In the scene where Ace just gets out of the empty dolphin tank at the football field, Roger Pedacter (Football coach) is trying to stave off the media. Take a look at the sweat stain on his shirt and see how it changes sizes.

Continuity: When Ace is at the mental hospital, inside the storage room, he steps on a piece of bubble wrap. He picks it up, looks at it and throws it to the side. Throughout the scene the bubble wrap moves away from the shelves then close to them again.

Deliberate "mistake": In the scene in which Ace is in the asylum, he breaks into a storage closet to view Finkle's belongings that were left behind when he escaped. At first the doorframe is such that the door closes against about an inch of wood, meaning the lock would be behind this wood, so Ace couldn't pry it open. In the closeup, the door's flush against the frame so Ace can use the sign to get between the door and the frame. In the wide shot it's back to how it was.

Continuity: At the end of the mission impossible music, where Ace is sneaking into the billionaire's private Aquarium, there is a plant in the hallway shown from outside of the building when Ace swings opens the door. But when he slams the door shuts and is inside the building no plant is there.

Revealing: At the very beginning, when the guy is hanging on to Ace's car and Ace drives off, there is a shot of the dog biting the guy, but if you look closely, you'll see that the dog doesn't even open its mouth. It just sort of brushes his hand.

Audio problem: Right after the "Mission Impossible" theme when he gets into the shark tank room, he slams the door, but you hear the door slam before it actually slams all the way shut.

Continuity: In the apartment crime scene, Sean Young says "we'll let you know if we find a tic", and the large grey-haired cop on her left chuckles, arms by his side. We then cut to a close-up of him with his hands on his hips, pushing his jacket to the sides, then back to the original shot with his hands by his sides again. The close-up itself is a bit weird - Sean Young should be right in front of him, but isn't visible. They must have used a later shot, because after about a minute, when everyone's moved around a lot, we see him back in exactly that position, only now the people visible fit the scenario better.

Continuity: In the opening scene, someone is crawling through the shattered rear windshield of Ace's car while it is in motion. They show a shot from inside the car and the guy has about half of his body in the car. When they show an outside shot, his hands are barely inside the car. Then, in the next inside shot, half of his body is still in the car.

Audio problem: In the scene where Ace gets attacked by Ronald Camp's shark, while he is being tossed about in the tank you can hear a crew member shout, "Great.". This may only be on the VHS version.

Revealing: When Ace's car flips over you can see the left wheel is elevated over the bush. If you look closely there is a wooden plank there to help the car lift itself over the bush. The other mistake in the shot is that there is no conceivable way the bush would have flipped the car. Unless there was something very solid in front of the bush, the car would have just gone right through the bush.

Continuity: When Ace is showing Melissa the Almanac after he leaves Camp's house, his hand position on the book changes between takes.
