Continuity: In the scene when the mom is making sandwiches she picks up a piece of meat and puts it on the sandwich in her hand but then when the shot changes she is taking that same piece of meat and putting it on the same sandwich, and you can see that she isn't taking another piece and putting on the sandwich because you can see that all she has on the sandwich in her hand is a piece of lettuce.

Visible crew/equipment: When Mitch and his brother are singing at the piano, a close up on Mitch's right ear reveals an ear-piece monitor that isn't there when the shot pans out towards the end of the scene.

Factual error: The license plates on Dan's car are very inaccurate fakes. The colors especially are way off. Certainly, the makers may use a fake sequence of characters the same way "555" phone numbers are, but the styling of the plate should look right. Real NJ plates are a pale yellow along the top 1/4 that fades to a very pale tan by halfway down. Dan's plate is a bright yellow (nearly orange) at the top and the rest is white. The numerals are also the wrong typeface. The mistake is made more obvious by the fact that real New Jersey plates are seen in the early portion of the film on other cars.

Continuity: When Dan throws the big rock, the surface of the water is very calm and smooth. When the shot changes, the water's surface is windblown and a wave is present, far bigger than what the rock would have made.

Continuity: In the scene during the credits, the right shoulder strap on Marie's dress has fallen off her shoulder. Her body turns as she dances in the circle and her right shoulder is not visible momentarily. When it becomes visible again, her strap is up. No one touched her and she did not "shrug" it up.
