Visible crew/equipment: After Josh tells Cher she's such a brat, at the start of the next shot which is the first close-up of Cher during the driver's test, just as she says, "I had an overwhelming sense of ickiness, even though I apologized to Lucy," the top of a crewmember's head, with his short wavy hair blowing in the wind, is reflected at the bottom of the Jeep's windshield, directly in front of Cher and the steering wheel. (01:11:55)
Continuity mistake: When Cher is taking the driver's test, she bangs the mirror. But then, when she turns the corner, the mirror is whole again.
Other mistake: When Josh and Cher are driving home from a party, they show a shot of the car. It's a blue sports car that passes a Hertz car rental sign. When Elton is driving Cher home from the party in the Valley, they show the exact same shot of the blue sports car passing the Hertz car rental sign.
Visible crew/equipment: Near the start, when Cher picks up Dionne in her Jeep, in Dionne's two closeups when she shows off her hat and when she says, "Well at least I wouldn't skin a Collie to make my backpack," the shadows of film equipment, crane and rigging are visible on the lawn as it moves along with the girls. (00:02:45)
Continuity mistake: The rearview mirror on Cher's Jeep keeps disappearing and reappearing, between close-ups and wideshots, throughout the film. (00:16:00)
Continuity mistake: Tai and Cher are hugging when they are watching Travis' skateboarding competition. Cher starts out on the left and Tai on the right. They hug in that position and then mysteriously end their hug on opposite sides.
Audio problem: When Cher and Tai are at the party and Travis comes up to them he has 2 cups of some kind of drink and all of a sudden you hear a sound that is supposed to be something spilling. I guess they assumed that it was supposed to be the beer spilling on Cher's shoes. Well as you can see nothing falls/spills from the cup, it is just sound effects.
Continuity mistake: When Dionne is driving Cher and Murray in his BMW on the highway and the tractor trailer comes up behind them, it appears to change lanes to pass them 3 times. However when the camera angle changes the truck is lined up right behind them again.
Continuity mistake: In the scene where Cher picks up Dion and they drive to school, Dion's nose ring appears and disappears with each shot. Same case for other scenes/shots throughout the film.
Revealing mistake: When Cher is robbed and she calls her brother on a payphone, she doesn't put any money in and she doesn't press enough buttons to be using a calling card.
Continuity mistake: When the group arrive at the Valley party you can see that the house is a single story, but later when Cher goes out to the pool the house is now a two story.
Continuity mistake: On the part where Ty and Cher are at Travis' competition, after they "make up" they sit down beside each other and they are toward the back with no people around them, yet on the next shot, they are toward the front and there's a bunch of people behind them.
Plot hole: After Cher is robbed, and calls Josh to get a ride home, she does not tell him where to pick her up. She just says she's in Sun Valley.
Suggested correction: Well it cut to when she was in the car with him. Maybe she called him again later offscreen to tell him where exactly she was or maybe he guessed where she was (maybe she had told him another time where she usually goes in Sun Valley).
Continuity mistake: When Tai is being held over the railing at the mall by the guys from Foot Locker, Christian begins to run towards her as soon as she screams. There is a shot of Tai, and then back to Cher and Christian. But Christian's motion resumes from exactly where he had been in the last shot of him, despite almost two elapsed seconds.
Continuity mistake: When Josh picks up Cher after she is mugged, the rearview mirror on Josh's car disappears when he pulls over to the curb.
Continuity mistake: When Cher is taking her driving test and is supposed to be changing lanes, she almost hits a biker. But if you look closely when she is actually just hitting the biker you can see that it is not her, but a professional driver. The next shot then goes back to being the real Cher.
Continuity mistake: When Cher is helping Josh and the other lawyer go through depositions, and screws up, the other lawyer yells at her and she runs up the stairs crying. However the view switches to Josh with the staircase behind him when she should still be in view on the staircase and she's not there.
Continuity mistake: When Dan Hedeya is sorting the mail, there is a close up of two peices of mail. The first is a letter addressed to Melvin Hamilton with 90210 zip code. The second piece, Cher's report card, is addressed as Cher Hamilton with the zip code of 90212. Cher's last name is Horowitz, as established earlier in the film. (00:19:56)
Audio problem: (This is extremely difficult to see and you have to concentrate to notice it). When Cher and Tai are talking in Cher's lounge room after the workout, Cher says "something good for mankind or the planet for a couple of hours", but her words don't match her mouth moving for 'hours'.
Continuity mistake: While Tai is in the livingroom, Cher and Josh are in the kitchen as Josh fixes himself a turkey sandwich. When they reach the livingroom doorway he's taking a bite out of it as he holds the sandwich is in his left hand, but next shot it's in his right as he continues taking a bite.
