Continuity mistake: Throughout the movie, Peg's hair frequently changes from scene to scene and within a scene. When her hair has a blue ribbon around a bun at the top, her side parts are sometimes higher/lower and straight/jagged. The length of her hair varies, as does the amount of curl on the bottom. One of most noticeable variations in her hair length and curl occurs during her speech to her new employees at Personal Expenditures Garnering. It changes several times from just to the shoulders to a few inches below her shoulders. Back views of her hair tend to be shorter and front views tend to be longer. (00:44:42)
Continuity mistake: At the restaurant, the amount of water in JJ's glass goes up and down a few times (although he is not seen drinking any and no waitress or waiter refilled his glass). (01:02:33 - 01:04:00)
