Continuity mistake: When Austin is typing to Sam from his bedroom, the very first book on the shelf in the background keeps changing, over and over again. This occurs near the start, when they are still unknown to each other, and also when he tries to write to her after the pep rally incident.
Continuity mistake: At Rhonda's house, when Sam says, "You sure do have a knack for taking something simple and making it beautiful," the red bowl is beside her. After Rhonda shows Sam the white gown, the camera pans back toward the table top and the lace mask suddenly and deliberately appears and is leaning against the bowl.
Visible crew/equipment: As Sam and Rhonda have Fiona's car confiscated, when Fiona runs out shouting, "I can pay for those parking tickets!" the crew's black mat is laid out on the walkway, but in the overhead shot when she tries to run away that mat is gone. (Visible on fullscreen DVD.)
Visible crew/equipment: When David and Ryan force Austin to sit on the bench and meet the bachelorettes (with 'Dating Game' music playing), the white actor's mark is visible on the ground before Austin covers it with his foot. Also, when David introduces bachelorette 1, then bachelorette 3 and after Mrs. Wells says hi to Ryan, the green actor's T-mark is visible at David's feet. (Visible on fullscreen DVD.)
Continuity mistake: At the start of the pep rally, Mr. Ames takes a seat behind Austin in the close-up. Next shot facing the crowd, when Coach steps up to the stage, Austin's father is gone - his seat is empty, but a couple of shots later Mr. Ames is still there. Additionally, Sam and Carter are also gone in the crowd shot.
Visible crew/equipment: As Austin is putting up the Cinderella fliers at school, David tells Austin that he listens to him but promptly gets distracted by a girl. At the start of the next shot, as the girl walks forward the red actor's mark is visible on the floor behind her, where she was standing until she got her cue. (Visible on fullscreen DVD.)
Continuity mistake: When Sam is sitting on the friendship circle you can see that her legs are crossed the entire time. When she texts Austin you see her legs and they are not crossed. In the shots before and after this one her legs are crossed.
Visible crew/equipment: When Austin is putting up the Cinderella fliers at school, just as he tells David and Ryan, "The phone's locked. I keep getting messages like...," the red actor's mark is visible on the floor behind Austin and the white actor's T-mark is visible on the floor behind Ryan. (Visible on fullscreen DVD.)
Continuity mistake: During Sam and Austin's dancing outdoors, Sam's hand shifts. In one shot it is completely over his shoulder and in the next shot it is on his shoulder. We see her hand the entire time so there is no time for her to move it without seeing it.
Continuity mistake: When Austin is putting up the "Have you seen Cinderella?" fliers, in one shot he puts up the second flier on the blue door on the lower left side of another flier, but in the following shots, the flier is near the center, then to the right, and then back near the center again.
