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. (00:58:55)
Continuity mistake: 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. (01:00:15)
Continuity mistake: When Ace 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. (01:00:30)
Continuity mistake: 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. (01:02:45)
Continuity mistake: When Ace is trying to work out what Einhorn 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. (01:03:30)
Continuity mistake: 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. (01:11:40)
Revealing mistake: 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. (01:18:25)
Character mistake: In the scene at Roger Podacter's condo building, you hear the reporter mention that he allegedly leaped to his death from his own 20th story balcony. As the camera pans down, you can see the flashlights and people up on his balcony doing the investigation. This is the 2nd from the top floor. If you count the floors as the camera moves down, there are more than 20 floors to this building. The number is actually closer to 30. Even though it is difficult to get an exact count of the floors, it is still possible to tell with 100% certainty that his unit was on a floor higher than 20.
Revealing mistake: In the scene where Ace visits Woodstock's secret office at the music club, pay attention to the computer screen when Ace asks him to tap into the aquatic supply stores to track the sale of equipment for transporting a dolphin. Woodstock says, "All right, we got marine winch, sling, feeder fish, 20,000 gallon tank..." As he is saying this, the computer screen shows a bunch of non-related items (plates, cups, concrete, stone) with crazy numbers that don't make sense. It was as if someone was in a hurry to create a fake spreadsheet to use in the movie that they just pounded on the keyboard and a bunch of numbers came out. If you look through all of the items, it's actually funny how they are so varied (dog food, speakers, sneakers, soup, chairs) and have nothing to do with the story. Many of the items also repeat with different sets of numbers.
Other mistake: When Ace and Dan Marino pass in their car, on their way to the Superbowl, the stadium in the background is the one holding the special event, yet there's no car in the parking lot.
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.
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.
Continuity mistake: 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.
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 mistake: When Ace is showing Melissa the Almanac after he leaves Camp's house, his hand position on the book changes between takes.
Continuity mistake: 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.
Continuity mistake: When Ace empties the filter from the water tank, he blows dirt off his hand to get a better view of the precious stone. He does not, however, remove all of the grime off his palm. In the close-up shot of his hand to visualise the stone, his hand is clean.
Continuity mistake: 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.
Character mistake: Ace claims the stone he found is triangular cut Orange Amber from a 1984 AFC Championship Ring. The stones in the actual 1984 AFC Championship Ring were not triangular cut Amber, they were round cut Diamonds.
Answer: He says, "I just can't do it, Captain. I don't have the power!"
