Audio problem: When Diamonds in the Rough are playing there is a point in the song where the guitars a strummed quickly and then abruptly stopped. The sound of the strumming stops and Wayne stops strumming, but J.D. is still strumming. We should hear his continued strumming but do not. (00:06:55)
Audio problem: When Dr. Phreak is beating up Jimmy's bubble he's saying, "I'm not mini," yet his mouth is not moving.
Audio problem: When the men are fighting in the street, Bridget and her friends are talking about who to root for, and Bridget's mouth doesn't match what she is saying at all.
Audio problem: When Fontana says "He's such a show-off" to her friends Lana and Anna at the beginning of the movie, her mouth doesn't move.
Audio problem: When the guy in Jack's truck says "You better pay for that camera", his mouth doesn't match his words.
Audio problem: When Hal is talking to Katrina, after he's been de-hypnotized, in the over-the-shoulder shot of him facing her, we hear him talking but his mouth doesn't start moving until he turns to look away from her.
Audio problem: Jennifer and the Captain exit the plane and stay there for several minutes while sirens from airport services howl, obviously to help them after such a chaotic flight. However, wider shots show that there's not a single car or person nearby.
Audio problem: When Cathy gets a telephone call in her yoga class we hear a Nokia tone, but she has got a Motorola telephone in her hand. (00:37:45)
Audio problem: During the failed kidnapping attempt at the mall, Nancy Sinatra's "These Boots Are Made for Walking" is playing over the mall sound system, and the song is badly edited to extend it for the duration of the scene. In the actual song, Nancy Sinatra famously says, "Are you ready, boots? Start walkin'!" only once. But, in this movie's chopped-up version, she says it twice.
