Other: In the scene where Andy is walking by the fountain in Paris, her phone starts ringing. When she checks to see who it is, Miranda's name and number shows up; however, if you look closely, the phone is actually showing an outgoing call TO Miranda, not FROM Miranda.

Continuity: In the last scene with Miranda, she enters her car from the left side, but is immediately seated in the right seat. There is no time for her to switch sides once she gets into the car. Nor is there any apparent reason why she would scoot from one side of the back seat to the other.

Continuity: When Miranda tells Andie that she wants the Harry Potter book, Andie goes back to her desk and her Sidekick is on her desk. She had put her purse down but not her phone because she never got a chance to pull it out.

Continuity: When Andy throws her sidekick into the fountain, she is holding it in one hand. The reverse shot of the face of the sidekick shows her holding it with both hands.

Audio problem: When Andy is talking to Nigel during the photo shoot in the park, her lips don't move during her last line of dialogue.

Continuity: At the very end of the film, after Miranda has sat down in her car and told the driver to "go"; it doesn't look like she's actually in it in the next shot when the car takes off as Andy walks by.

Continuity: When Miranda puts her coat and bag on Emily's desk in the scene where Andy has to tell Emily she isn't going to Paris, the bag is standing up. The next shot shows the bag flat on the desk and turned.

Continuity: When Andy is talking to Nigel at the fashion shoot she tucks her hair behind her ear and when the shot changes it's completely over her ear.

Continuity: When Andy and Miranda are in the limo in Paris, they pull up to the curb and there is a bunch of press waiting as Miranda opens the door. However, when the shot changes, it is not the same group of people - in particular, there is a balding photographer who should be standing right there but is nowhere to be seen. It all happens too quickly for that much change.

Continuity: In the scene where Andy is sitting in the restaurant with her father, you see her father taking of his glasses. In the next shot you see the father from the back, taking of his glasses again.

Continuity: This one has to be watched carefully but can be seen without slow motion - when Emily hits the taxi's windshield, the front shot shows her hit the hood with an orange package under her - it looks more like a box than a bag - and her purse in her right hand. Before she was hit she also had a small orange bag in her hand. A shot later, the side view of the accident shows 3 orange bags flying through the air, and her purse is on her left arm, not on the right as it should be.

Continuity: When Emily is explaining to Andy about the 'Book,' she tucks her hair behind her right ear. When she straightens up her hair is untucked.

Continuity: Emily has a bad cold/flu the day of the benefit Miranda hosts - her nose is extremely red and she's congested. Miranda tells her Andy will have to go too, so Emily shows Andy photos of clients to memorize; suddenly she has no sign of a cold at all - the redness just disappears, which wouldn't happen that quickly. That night it's back in full force, just as it was earlier in the day.

Continuity: When Nigel is toasting himself about what he thinks will be his new job, the glass is in his hand. The next shot shows his hands are empty and he grabs his head with both hands and walks to the window. Andy then brings him the glass.

Continuity: In the scene in Paris where Christian kisses Andy, from one angle her head is tilted to the right as they kiss, then the shot changes and they are now tilted in the opposite direction. This happens almost every time the angle changes throughout the kiss.

Continuity: In the restaurant where Andy is giving her friends presents, she hands her friend a little clear case of Clinique products, but when she's putting them in her friend's hand, she is also holding a blue box when she wasn't before.

Continuity: In the scene where Andie's talking to Emily in the hospital, Andie puts her purse down. When they cut back to her again, she puts it down again.

Continuity: When she sings the "Happy Birthday" song to her boyfriend she carries a little cake with a burning candle on top. The length of the candle changes from view to view and appears longer, shorter and longer again.

Continuity: When Andy first meets Christian at the party, her hair changes throughout the scene. First one side is in front of her ear, then it's tucked behind it, then it's in front again.

Continuity: When Andy answers the office phone for the first time, the blue post-it notes that had been right next to the monitor's base, have moved a couple of inches, even though no one touched them.
