Mean Girls (2004) - 64 mistakes

Factual error: In one if the final scenes where Cady is competing against contestant Kraft, Kraft states that the answer to the math problem is 'the limit is negative one' and is told the answer is incorrect. It is actually correct.

Continuity: After the Halloween party, when Cady walks into Damian and Janis' house, Damian gets scared and tosses all of the popcorn out of his bowl. In the next shot of Damian his bowl is full again.

Continuity: When the principal is introducing Cady to the class, the amount of donuts on the desk changes between shots. In some shots there are two donuts on top of the donut box, and other shots there are no donuts.

Continuity: When the main character is confronted by her crush in her room, she puts her drink on a pile of CDs, the CD pile starts to fall in the background as there is a shot of the guy, a split second later the cup is on the table next to the CDs, and the CDs are piled differently.

Continuity: When Cady runs into her teacher on the first day of school and spills coffee all over her, look at Tina Fey's pants. It looks like she is wearing rubber pants when the coffee is spilling down her front. The color of the pants also change during this shot.

Continuity: When The Plastics go to Regina's house for the first time, Karen walks over to the counter to put her bag down twice.

Continuity: When Cady, Janice and Damian are in class talking about different things, like watching a movie, and Cady tells Janice she can't see her art show because she going to Madison etc., Cady is applying lip gloss. She holds a pocket mirror and in shots of the mirror you can see Cady holding the pink tube of lip gloss in the same hand, then when it cuts to wideshots, the tube isn't in her hand. The pink tube of lip gloss also has no lid on it, yet near the end of the scene a blue long lid appears on the pink tube.

Factual error: The mall that the plastics state they are going to, Old Archard as stated by Cady, is an outside mall. However, the mall they go to is an indoor mall.

Continuity: When Cady is starting her first day of school and her parents are saying goodbye, she starts to walk up to the high school. Her dad starts to walk away while her mom stays standing there. In the next shot where it shows Cady's face, her mom and dad are still watching her together.

Continuity: When Regina becomes angry, and writes the horrible message in the burn book about herself to frame Cady and the others, the handwriting changes between shots. Look at "DO NOT TRUST HER" and "She is a fugly slut." - The handwriting changes noticeably, and "fugly slut" changes a lot - she writes it so the "g" and "y" have curled ends, yet it cuts to her sticking her photo in, and the ends to the tails on the "g" and "y" are straight. The line under "fugly slut," and the exclamation mark both change too.

Continuity: When Cady and Gretchen call Regina, without Regina knowing Gretchen is on the line, and then Karen is called, it is definitely night time outside the windows of Cady and Gretchen's. However, daylight pours in Karen and Regina's windows. They are all calling each other at the same time.

Continuity: Cady breaks up her Spring Fling tiara that she receives. On stage, she breaks it up into many pieces and throws them out into the crowds; it is clear that the amount we see being thrown into the crowds is a major amount of pieces - almost too much from just one tiara. However then when she leaves the stage, we see her holding approximately half of the tiara still. This would not be possible from the aforementioned amount that Cady has already snapped off and thrown into the crowd.

Revealing: In the scene where Mrs George is taking pictures of the girls for the Halloween concert you can see that the camera is turned off.

Continuity: When Cady enters the dance after the Mathletes competition, her sleeve is down past her arms and we cannot see her hand. In the next shot, the sleeve is rolled up and her hand is visible.

Continuity: When Cady is trying to get out of going to Madison, watch the level of her Dad's glass of water. From the first shot of the table to when he picks it up whilst saying "I think Cady's old enough..." the water level lowers.

Continuity: In the wake of the candy-cane grams, Gretchen's arms change from above her shoulders to on the desk.

Visible crew/equipment: Before Cady enters the house, when one of her best friends is watching a movie the reflection of a crew member is visible on the TV.

Factual error: The snake that Cady's dad is shown holding in the clips from Africa is a Burmese python. These snakes are not found in Africa.

Continuity: In the winter talent show scene, you see Gretchen go to kick the boom box in hopes of fixing the skipping CD, but when she kicks it you see it start to just fall off the stage. Yet in the next shot the CD player shoots forward and hits Gretchen's boyfriend, as if she had kicked it a lot harder than she actually did.

Deliberate "mistake": When Cady is breaking the 'plastic' crown into bits and throwing the pieces to people in the crowd, it's not possible to have that many pieces from that one crown. She must give out at least 7 or 8 big chunks, which just doesn't truly reflect the size of the crown.
