Factual errors: The first time Trip and Paula are on the boat, Trip jibes, and the mainsail and boom re-set but he never releases and trims the jib.
Factual errors: During a sailing scene, a discussion involving nautical terms refers to turning a sail boat as "jibing" and "coming about" which is in part incorrect. Rather this discussion should describe the two ways to come about: a "jibe" which is a downwind turn and a "tack" which is an upwind turn.
Continuity: When Trip and Jeffrey are drinking under the boat, Trip takes the plastic rings off of his beer and throws it on the ground. In the close-up of Trip drinking his beer, the plastic rings are still attached to his beer.
Continuity: After Tripp and Paula get off the boat, when they were caught by the actual owner, a close up shot shows Tripp's arm around Paula, and then a long shot, his arm is not around her.
Continuity: Kit's right arm as she and Paula have a drink; also, her left index finger is pointed in one shot then isn't in the next.
Factual errors: The BB gun used in the film is a Red Ryder as produced by Daisy. There is a reference to "pumping" 2 times, however, this is a simple weapon and can only be "pumped" one time.
Revealing mistakes: Obvious stunt double when Tripp is riding the bike - the stunt performer has a tattoo above his right ankle.
Continuity: During the entire sailing scene, the boat cuts through the water in some shots but is stationary in other shots.
Continuity: The level of Al's cereal and the position/amount of Tripp's scrambled eggs and pancakes during breakfast.
Continuity: The shots of Tripp with Mr. Axelrod and of Mr. Axelrod first walking toward the boat were clearly shot later in the day from the other shots in the scene.
Continuity: When Paula is talking to Tripp's parents, and they are drinking iced tea, the amount in the glasses change, and Sue's lemon changes positions.
Continuity: When Tripp is eating with his friends, Tripp changes between having his fork in his hand, to nothing in his hand, to having a drink in his hand, back to nothing, without showing him switching items.
Continuity: Toward the end of the movie Trip is talking to his mother. She is ironing and places a pair of jeans on the ironing board and prepares to iron them. Also on the ironing board is a pile of folded clothes. The next time you see her she has the folded clothes in her hands but there are no jeans on the ironing board.
Continuity: Near the end, when Paula and Trip are talking while everyone is eavesdropping, the action figures on the shelf behind Paula change positions between shots.
Revealing mistakes: When Tripp and Paula come back from a date, they go to Paula's house and see Kit on the balcony. Kit is supposed to be nude, but you can see that her chest is covered through the branches.
Continuity: In the scenes following Tripp's chipmunk attack, his bandage is on the wrong hand.
Crew or equipment visible: When Tripp is showing the boat to the couple, a reflection of a person sitting (wearing jeans and work boots) in a director's chair is showing on one of the boats.
Errors in geography: The movie supposedly takes place in Baltimore, MD, yet when they go to Ace's house, there are palm trees in the yard.
Factual errors: On Tripp's car there is no front plate. In Maryland where the film is set, there are license plates on the front of every car.
Continuity: Jeffrey is missing at least one of his front teeth until the end when he has all of them.
Factual errors: During one scene Paula yells "Go Omaha." Later Tripp asks if she wants a "Royals foam finger." The Omaha Royals are a minor league team in the Pacific Coast League. They play no teams on the Atlantic coast. The film was actually filmed in New Orleans. The director did not want to change the script at the last minute. The teams playing were actually the New Orleans Zephyrs and the Omaha Royals.
Continuity: When Kit and Ace are attempting to revive the bird, Ace pulls the bird's beak apart. The following shots alternate between an open and closed mouth bird.
Continuity: Towards the end of the movie when Tripp and Paula are having the conversation with Tripp tied to the chair, Paula's make-up keeps changing. She has different eye make-up and different lipstick color.
Revealing mistakes: In the closing scene, the sails on the boat are up while the boat remains motionless.
Audio/visual unsynchronized: When Tripp is grabbed of his surfboard by the dolphin, he is pulled off to his right, therefore meaning the dolphin grabbed his right foot. However, in the next scene, he is shown being pulled by his left ankle.
Continuity: When Kit is talking to Paula in the kitchen after breaking up with Tripp, Kit pulls up the right side of her sweater onto her shoulder. However, when the show her again, it's off her shoulder. Then, when Paula walks out of the kitchen, the sweater is back on her shoulder.
Continuity: When Trip is in the water with the dolphin at the end, the position of his sunglasses changes repeatedly between shots. At some points they've disappeared altogether.
Continuity: In the dinner scene with Paula and Tripp's parents, Trip drains all of his wine. A few shots later, his glass is 1/4 full of wine and he never picked up the bottle to add more.
Continuity: When Tripp is tied up in the chair the camera cuts to a shot of his feet turning him to his right and putting the stairs in the background directly behind him. Then the camera cuts to a head shot of Tripp and the stairs are on his left, then cut back to feet and stairs are directly behind him as he taps his right foot.
Continuity: When Tripp is bitten by the chuckwalla, he is seen being bitten on his right index finger on the anterior aspect, but once he wakes up after the fall it is his right middle finger that is covered in blood, and there are other times where his index finger is clearly seen with no injury.
Continuity: When Paula and Tripp are walking into his parents' house there are two cars parked across the street but when they enter the house a few seconds later the cars are gone.
Continuity: The same car is used by both Demo and Kit, when it is supposed that they each own their own car.
Revealing mistakes: Some shots of the surveillance video have "TCG" plus numbers at the bottom of the screen. TCG stands for "time code generator", and is only created in post production, as in an editing program. It would never appear as live video. From the format, it appears to be generated by the Final Cut Pro NLE software.
Continuity: When Tripp is showing Paula how to shoot the paintball marker, he is clearly rolling the trigger and the marker is not shooting so apparently it isn't on. But when Paula gets the marker in the next shot she shoots Ace in the foot. The marker is electric and you have to cut it on to shoot it. You couldn't see either one of them cutting the marker on so Paula shooting the marker would have actually been impossible without cutting it on.
Continuity: When Trip sees Mr. Axelrod coming, he packs up and warns Paula about who he is. As he gets up and climbs over to the dock, you can see Trip isn't wearing any sandals or shoes on his feet. After they get done talking to Mr. Axelrod Trip goes to chase Paula, and he suddenly has shoes on. He is not seen putting on shoes in between those two times.
Continuity: When Paula is leaving Tripp's house, she knocks over the vase with her left shoulder, but then is seen continuing to knock it over and try to catch it with her right hand, going backwards. Even if she was walking forward and tried to turn to catch it, her right arm would have gone in back, not front.
Revealing mistakes: In the scene where Terry and Kathy are cuddling, the body stocking that Kathy is wearing is obvious (between her arm and her neck/face)
Revealing mistakes: When Ace fires up the laptop computer to spy on Trip and Paula, the computer screen changes screens before Ace actually presses the key on the keyboard to do so.
Continuity: In the kitchen scene, there is a white Le Creuset tea pot heating water on the stove top. It is missing the whistler cap from the spout, yet when it is off camera, you hear it whistle to signify the water is boiling. Whistling is impossible without that cap.
Revealing mistakes: The coffee shop patrons watch the real-time showdown between Tripp and Paula on the jumbo screen via Ace's laptop as a series of shots, which is impossible.
Errors made by characters (possibly deliberate errors by the filmmakers): Paula tells Kit that she has "a fiduciary responsibility" to fulfill her contract. A Fiduciary is someone who acts as the legal caretaker of another's rights, assets and/or well-being. This certainly isn't the case here.
Errors made by characters (possibly deliberate errors by the filmmakers): The vet gives the dog the injection from outside the bandage with the needle inverted instead of through his IV.
Continuity: Tripp's glasses move while he relaxes with Paula at the chair store.
Continuity: On the evening that Trip prepares dinner his parents and Paula are seated at the table. Trip stands to announce a toast with a glass of wine in his left hand. He switches it to his right hand as he starts the toast, but during the announcement the glass disappears and reappears at the end of the toast.
Continuity: At the end of the paint ball scene -- Paula's jacket goes from being on, to around her waist as she is walking towards the guys.
