Continuity: At the end of the valley party, Cher and her friends are walking to the car. When she gets in she is holding a snowman that is glowing but you can clearly see that the cord is not plugged in.

Continuity: When Cher is taking the driver's test, she bangs the mirror. But then, when she turns the corner, the mirror is whole again.

Continuity: When Cher is held up by the guy with the gun after the valley party, he tells her to get down on the ground. Take a look at her necklace - it's a small silver heart on a silver chain. She gets down on the ground, counts to 100 (3) and gets up again. check out the necklace now - it's still the silver chain but the pendant on it is one of those name ones that says 'Cher'.

Other: 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.

Continuity: 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.

Continuity: 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: During the part when Cher and Tie 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: 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.

Continuity: 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.

Other: When the group arrive at the Val party you can see that the house is single story but later when Cher goes out to the pool the house is now two story.

Continuity: 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.

Continuity: 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: In the scene where Josh picks Cher up after being mugged, they are driving and talking in his Honda Civic Hatchback. When they do an outside shot in the same scene, they used a clip of Elden's Chevrolet Camaro.

Continuity: After coming home from the party, in the very next scene after the red hair clip suddenly appears in Cher's hair (as mentioned in another mistake), it changes to a silver clip and the red one is now on the other side of her head.

Continuity: 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.

Revealing: 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.

Other: On the back of the Clueless movie box, it says that it is "not easy being the most popular girl at Beverly Hills High..." but Cher goes to Bronson Alcott High School in the movie. The name is said and there are also a couple of scenes where you can see the initials BAH - most noticeably on the sweater of the gym teacher when Cher is trying to get her grade changed.

Continuity: When Cher invites Christian over, she's wearing a lot of eyeshadow. Lots of pink and lots of colour. It's even clear after she falls off the bed. But when she shows him to the door, which is right after her falling off, her makeup is different.

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.

Audio problem: (This is extremely difficult to see and you have to concentrate to notice it). When Cher and Ty 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'.
