When Janey and Lynn are riding in the bus on the way to the contest, her hair is not rolled; however, when they run into the tv studio, her hair is perfectly rolled and when she runs to Jeff, she has on dancing shoes.
In the dance tryout scene after Lynn and her partner are cut and Lynn goes after him, you can see Jeff's stunt/dance double in the foreground (wearing the red sleeveless shirt). You can also apparently see Sarah Jessica Parker's dance/stunt double instead of SJP during the same scene.
In the scene where Sarah Jessica Parker is in the bath tub, you can see a man's head at the bottom of the screen if you look quickly.
There's a scene where Janey recieves a phone call while in the bathtub. Her little brother answers the phone, and goes into the bathroom to tell her. You see SJP getting out of the tub and into a robe. She exits the bathroom to take the call, and the little brother walks out after her. Gross! Does that mean she got out of the tub and into her robe with him standing in there? Um, ew!

Janey's hair was also up in the bathtub scene and it is down when she walks out to answer the phone.
