13 Going On 30 (2004)

Continuity mistake: Towards the end of the film, Mattie hands Jenna the dream house he made for her 13th birthday. There is hardly any "wishing dust" on the roof. However, when she goes outside and sits on her front porch, there is plenty of wishing dust all over the roof of the toy house now.

Continuity mistake: In her apartment Jenna walks out into the hallway, looks at herself in the mirror and stumbles backwards over the shelf behind her. There is a short stack of magazines on that shelf, yet when Jenna looks at herself in the mirror the stack of magazines is at least three times as high in the reflection. (00:14:10)

Continuity mistake: When the six girls arrive for the party, in the first shot Tom-Tom tosses her blue jacket, then the second girl lays her red jacket and the third girl starts to put her pink jacket into Jenna's arms. Yet, at the start of the next shot facing Jenna, she holds only the blue jacket, since the red jacket is gone, the pink jacket is placed in Jenna's arms on top of the blue jacket and then the red jacket is thrown into her arms from off camera, before the rest of the girls dump their jackets into her arms. Then in Jenna's close-up, the jackets are positioned very differently in her arms. (00:08:15)

Trivia: Wrong places at the wrong times - the man who is hit by Jenna's thrown shrimp tail early in the party is the same one whose drink receives her dropped pina colado fruit.

Trivia: When Jenna wakes up as 30, she is in the same apartment the 30-year-old woman in the magazine was in when she was 13.

Jenna: You are rude, and mean, and sloppy, and frizzy - and I don't like you at all.

Jenna: What happened?
Matt: I don't know. I can pretty much peg it to your 13th birthday party, when you were in the closet playing that game. Spin the Rapist?
Jenna: Seven Minutes in Heaven.

Jenna: Wait, listen to me. I'm 13.
Lucy: Jenna, if you're gonna start lying about your age, I'd go with 27.

Question: After it's all over and the 13 year old Jenna kisses the 13 year old Matt, Jenna said something like, "I gotta show you something." What was it?

Question: In the meeting scene where Richard tells the Poise team that they have to redesign the magazine, Jenna has a red thing on her finger that she keeps chewing and biting. What is it?

Question: When Jenna has turned 30 and is going to the magazine party she has a dress on then asks her 13 year old neighbour if she can see her underwear to which the girl replies something like "I think that's the point." They then smile and laugh to themselves. Could anyone explain this joke?
