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 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.

Continuity mistake: While Tai is in the livingroom, Cher and Josh are in the kitchen as Josh fixes himself a turkey sandwich.

Continuity mistake: When Josh is taking Cher driving for the first time and Josh says "This is America we drive on the right side of the road." You see him saying that and then there is a cut of Cher and you see the curb like it's right next to her but you also see the curb right next to Josh - could be a one lane street but when they show you the car it is a 2 lane street.
Continuity mistake: At the party Tai, Cher, Josh and Christian are at, Tai asks Cher what to do with her shirt and Cher tells her to tie it around her waist. The film cuts to the band and when it cuts back to Tai, she's wearing her shirt again. The film again cuts to something else and when it cuts to Tai she isn't wearing the shirt, nor is it tied around her waist.
