Corrected entry: In the scene with Julia and her friend Kit on a patio, they sit at a table. In the middle of the scene, Kit takes a bite out of something in a bowl that must have magically appeared.
Corrected entry: In the beginning of the film, Vivian, (whose face we haven't seen yet) colors in her boots with a black marker held in her right hand. Near the end of the film, as Vivian is getting ready to leave the hotel and she's signing the papers, she uses her left hand. Julia Roberts is, in fact, left handed, as opposed to the stand-in used in the initial shot.
Corrected entry: At the end of the movie we see Vivian in the back of the limo. The next day Edward is supposed to be in the same limo, however the interior is completely different. (For easy reference, Vivian's limo has a grab handle and Edward's does not.) You will see lots of differences once you look. For instance, out the back window of Vivian's limo you can see that wing spoiler. You can't see the wing out of Edwards back window, however you can see the wing from the exterior shot of Edward standing up through the sunroof of the limo.
Corrected entry: In the shopping spree scene, when Vivian leaves the first store with her bags, she has a black clutch purse under her right arm. She then stops in the store that refused to help her the previous day and she holds both arms straight out, showing the sales people all her purchases. There's no clutch purse anywhere to be seen. Then when she enters the hotel, it's back.
Corrected entry: When Gere and Roberts are taking a bath, the first scene shows Gere's toe touching the bath tap. But in the next scene they have the bath tap on their right.
