Continuity: After Reuben has used Polly's special "Sponge", he stands at the door with the sponge wrapped in a plastic bag without anything printed on it. The next shot of the bag shows that it has red and blue printing.
Factual errors: Ferrets are usually as quiet as rabbits. When they get excited, they often do a "happy dance" and make sounds very similar to that heard in the movie. However, the "whining" sounds from the ferret behind the closed door are not normal.
Continuity: As the plane approaches St. Barts, its shadow can be seen on the water. The plane is clearly a single-engine aircraft. As it lands and taxis in, it becomes a twin-engine plane.
Crew or equipment visible: In the very last scene, when the ferret runs into the palm tree, you can clearly see tracks in the sand from the animatronic ferret's wheels.
Continuity: During the scene at the Hell's Kitchen Community Center, Reuben's tie is knotted with a deep dimple. Seconds later, outside the community center with Sandy, the tie has no dimple.
Continuity: When Reuben and Sandy are at the pizza place, Reuben rubs the straw paper into a ball. In the next shot, he's wrapping it around his finger.
Continuity: When Reuben is playing racquetball with Leland Van Lew, Leland smacks his face into the wall and his mouth begins to bleed. When Reuben points out the bleeding, Leland reaches into mouth and pulls out a tooth. He is clearly missing a tooth near the front of his mouth. The next time we see him, he is smiling, and he has all his teeth.
Continuity: When Reuben and Lisa are lying on the beach, there is nothing in the background in the first shot of Lisa. In the second shot, you can see Claude's boat and people lying on deckchairs.
Continuity: In the last scene, when Polly and Reuben finish talking to Claude, they wave at Leland in his boat just off the shore. Immediately after, they are walking toward the sea, with no boats in sight and the sun setting.
Crew or equipment visible: In a shot of Leeland's boat, the wake of the camera boat is clearly visible in the foreground.
Continuity: The first time Rueben walks up to Polly when she is outside her apartment he runs across the road with no cell phone in his hand. When the shot switches to her then back to Rueben, he has his phone in his and is faking a phone call.
Factual errors: The poster for Crocodile Tears shows a PG rating, but the rating text underneath is for an R-rated movie (it refers to under 17s requiring an adult guardian).
Continuity: When Reuben "accidentally" runs into Polly outside of her apartment, Polly's keys appear and disappear from her right hand throughout the scene.
Crew or equipment visible: When Polly and Reuben are arguing in the boat, equipment can be seen reflected in the television on the wall to the left of Polly. This cannot be Reuben because he is completely opposite of Polly at the time.
Continuity: When Reuben and Polly are at the Mid-Eastern restaurant, Reuben is perspiring profusely; his face and shirt are soaked with sweat. When they go to her apartment, his shirt is dry and seems freshly pressed.
