Continuity mistake: When Lizzie is in her room sorting out clothes, her Mum comes in and informs her that she can now go to the party. During the scene that follows with Lizzie and her Mum talking on the bed, Lizzie's necklace continues to hop in and out of her tee-shirt between shots.
Continuity mistake: When Lizzie is at her locker, she is looking at the wishbead necklace that she and Miranda had made. The necklace is hanging from a peg inside the locker. She then spots Miranda with Kate and then closes the locker door, only now the necklace is missing from the peg.
Continuity mistake: When Mrs. McGuire walks over to check the calendar to see if the day of Lizzie's party is free, there is a green highlighter hanging under the picture of their Grandmother. Yet in the close up of the picture, the highlighter is missing, then back again. Also, the sheets surrounding the photo move positions.
Continuity mistake: When the camera pans to an overhead shot of Lizzie lying on her bed, sulking about not being able to go to the party, look at the books opened on her bed. In the close up of her, when her Dad knocks at her door, the pages that the books were open at have now changed, as well as the books positions, and the way Lizzie has her arms folded as well.
Continuity mistake: When Mrs. McGuire is on the phone talking about lying, Lizzie begins to argue that if she can lie, why can't she. In one shot Mrs. McGuire puts the phone down to her shoulder to cover the earpiece but in the next shot (from behind) she has the phone back up to her ear again.
