Continuity: In the end, when Dave is chasing Ian, we see many headlights behind him. However, once the chipmunks hop up and Dave slams his brakes, we see no lights and no cars pass him. Also, the whole time they are talking, no cars pass again. When Alvin steers the car there are all kinds of cars again flowing both directions.

Continuity: The pumps of chocolate sauce in the chipmunks' coffee disappear too quickly for them to drink it all.

Continuity: At the Orpheum finale, the chipmunks tear off their concert clothes, revealing them to be nude underneath. After that, they are captured by Ian and trapped in a cat carrier. Later, when they reunite with Dave, they are in their regular clothes. It's obvious that they didn't bring their regular clothes to the Orpheum and there's no way they could get them when they're trapped in a cat carrier or when they escaped. Submitted by Brad

Continuity: Towards the beginning when Dave leaves the record label (after he steals the muffins), downstairs you can see a girl in a pink top, a delivery guy and a black guy in beige boots. The girl in the pink top passes Dave, then it cuts and you see her in front of Dave. Then it cuts again and you see her behind Dave and going around a corner. Also, the guy in the boots does the same thing a few times. And the delivery guy comes up close to the shot in the end, then they show him again just getting close.

Continuity: When Dave chases the chipmunks along the kitchen counter, the mess on the counter keep changing arrangement between shots. Submitted by Hamster

Continuity: When the chipmunks start practicing for the first time with Ian, Ian gives Simon "cooler" glasses that he should use it from now on. However, in their tour shots he's still using his old glasses. Much later in the movie he is also seen rummaging through a desk cabinet for his his old glasses which he found to be already bent.

Other: For a chipmunk who is so blind he cannot see a toaster waffle land right in front of him Simon, is really good about placing the bowl directly under the flow of cheese balls. He stops going back when the balls stop hitting his head, then looks up and precisely moves the bowl to catch the bulk of cheese balls coming down.

Continuity: When the chipmunks are hiding under bowls and slowly moving across the counter, the bowls keep changing location, whenever the chipmunks stop moving. Submitted by Hamster
