Continuity: When Finkle/Einhorn is stealing Snowflake, he has his hands on the side of the tank. Look at which finger his Championship ring is on. Then when he puts his hand in the water, it's now on a different finger.

Visible crew/equipment: When Ace Ventura is checking out the tank at Ronald Camps party (looking for Snowflake), as he's holding the fish over the water, whistling and saying "Here Snowflake", you can see the tip of the sharks nose, waiting to jump out of the water.

Continuity: When Aguato takes a swing at Ace, Ace throws him down on the bug. There is no way he would have been in a position to do that, the bug was right at his feet.

Continuity: In the scene where Ace is trying to find a connection between Finkle and Einhorn, there is a shot of his monkey walking along a mantelpiece to the right hand end.  There are 2 photos in frames on the mantelpiece, one of which is right up against a heavy book that is flat on the mantelpiece.  In the next shot, zoomed in on the monkey jumping on the book there is no sign of the photo that should be touching the book.

Revealing: After Ace loses the guys in the car chase who kidnap Dan Marino, Ace goes hurtling through the park in his car and smashes through a picnic table. Just before his car flips you can see his windshield is smashed but no holes through it. As the car flips over the bush there is a sizeable hole in the windshield on the drivers side. Its likely the hole was for the stunt driver to look through on the flip. Ace in his car has to keep his head out the window to see anything in front of him (because of the smashed windshield). On the flip the guy has his head in the car. Later on the hole has fixed itself. We see this as Ace is driving Dan Marino to the Superbowl the windshield is still smashed but no hole and throughout the film its made very clear Ace doesn't have the money to fix it up at any point.

Continuity: Near the beginning when Ace is in the parking lot of the stadium for the first time, there is a person walking in the background as Ace swerves his car. In the next shot, it shows two people watching him drive, and then when it goes back to Ace's driving, the man walking in the background is gone without having enough time to walk out of the camera's line of sight.

Continuity: When Ace is talking to the dog in Roger Pedactors apartment (after his death), he picks up the dog when Einhorn approaches. As he is picking up the dog he places his left hand around the dogs neck. In the next split second shot his left hand is around the dog's body.

Continuity: In Ace's fight scene with Einhorn, he pulls her jacket down around her elbows, and she retaliates by kicking him in the groin. A split second later, her jacket is on properly again.

Continuity: When he is in the aquarium tank (just after he says "I've got to, mister!"), he leans down with his glasses in his left hand. He's supporting his weight on his hands so can't move them, but in the next shot from behind his left hand's flat on the ground with no glasses in sight.

Continuity: When Ace is dressed as a HDS delivery man, he starts playing soccer with the package he is carrying. After that you can see that the box is open at the top. When he is at the door, you can see that someone has put new tape on it to close it again.

Continuity: Melissa says 'Why did it have to happen now, two weeks before the Superbowl?' She later says to Ace that it is Superbowl Week, and that someone stole Snowflake last night.

Factual error: When Snowflake is being stolen at the beginning, he makes the high-pitched noise that dolphins make even when he is out of the tank; those high peals are made underwater through carrying sound. He wouldn't sound the same out of the water as he did under it.

Continuity: When Ace enters the bathroom at Camp's mansion, a towel falls to the floor from the door. However, when he exits the bathroom soaking wet, there is a closeup of his shoes and the floor and the towel is gone.

Continuity: When Ace looks through Finkle's stuff he holds up two knitted coasters. They change hands between the two shots.

Continuity: In the scene where Ace is trying to figure out the Finkle/Einhorn connection there is, what looks like, an air horn on the far end of the table to the right of the dog. A shot or two later when it shows the dog's hair around the picture of Finkle you can see the end of the horn laying right next to the dog on his left side.(This is visible in the screen shot already on the site that shows the dogs hair position changing.).

Revealing: When the bad guys are shooting at Ace, he catches a bullet in his teeth. However, he goes from his lips being tightly shut to suddenly having the bullet in his teeth, obviously hiding the bullet in his mouth.

Continuity: When Ace rummages around in the filter, his hand gets dirty as he grabs hold of some stuff. When he blows the muck away, and is left with just the gem, it is completely spotless.

Continuity: At the beginning of the film when Ace is kicking the box down the apartment's hallway and he says, 'We're going downtown.', before he says that the box is up against the wall in a normal position, after the close up of Ace saying this, the box has moved to a different position.

Other: Why are there so many people waiting at that one bathroom where Ace entered at Camp's mansion? Seeing as how he is extremely rich, he must have many other bathrooms in his giant house.

Continuity: At the start of the film, the lift doors change colour from when Ace steps into the lift and when he steps out.
