During a sailing scene, a discussion involving nautical terms refers to turning a sailboat 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.
Avian CPR is performed with the bird in front of the human's face, tilted slightly away, with one hand supporting its head and the other its body. Ace performs the CPR with the bird on the table as if it were human.
When Tripp and Jeffrey are drinking under the boat, Tripp takes the plastic rings off of his beer and throws it on the ground. In the close-up of Tripp drinking his beer, the plastic rings are still attached to his beer.
When Tripp is tied up in the chair, the camera cuts to a shot of his feet turning him to his right, putting the stairs in the background directly behind him. The camera cuts to a head shot of Tripp showing the stairs on his left, but then it cuts back to his feet and shows the stairs directly behind him again as he taps his right foot.
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.
When Tripp 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 Tripp isn't wearing any sandals or shoes on his feet. After they get done talking to Mr. Axelrod, Tripp goes to chase Paula, and he suddenly has shoes on. He is not seen putting on shoes in between those two times.
In the scene where Kit and Paula are in the kitchen talking about Paula's fun day out boating with Tripp, the bottle of Moet champagne on the kitchen counter moves so that the label is facing the camera.
On the evening that Tripp prepares dinner, his parents and Paula are seated at the table. Tripp 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.
When Kit is talking to Paula in the kitchen after Paula breaks up with Tripp, Kit pulls up the right side of her sweater onto her shoulder; however, when the camera shows her again, it's off her shoulder; then, when Paula walks out of the kitchen, the sweater is back on her shoulder.
When Paula leaves Tripp's house, she knocks over the vase with her left shoulder, but then is seen continuing to knock it over and trying 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.
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.
Towards the end of the movie we find out that Justin Bartha's character, Ace, bought his house from his parents to avoid having to pay the inheritance tax when they pass away. The Federal inheritance tax in 2006 was on inheritances starting at $2 million. There are state inheritance taxes as well, but Maryland, where this movie is supposed to take place, exempts direct descendants of those receiving the inheritance from the tax.
When Tripp is showing Paula how to shoot the paintball marker, he is clearly rolling the trigger with the marker not shooting, apparently not on, but in the next shot when Paula gets the marker, she shoots Ace in the foot. Since the marker is electric, you have to cut it on to shoot it. You couldn't see either one of them cutting the marker on. Without cutting it on, Paula shooting the marker would actually be impossible.
In point of fact, the Miss Paula is a "ketch" i.e. two masts, the rear-most of which (mizzenmast) is set ahead of the rudder post. Boats of this type most often exhibit strong "weather helm" - a tendency to turn into the wind and stop moving if the tiller/wheel is left untended. Such is the case after Trip is knocked overboard.
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.
When Tripp is grabbed off his surfboard by the dolphin, he is pulled to his right, meaning the dolphin grabbed his right foot; however, in the next scene, he is shown being pulled along by his left ankle.
