Continuity mistake: When John says, "You offend reason sir," Peter floats up. The large light fixture is hanging from the ceiling. However, in the next shot facing Peter when he says, "Just think happy thoughts," where is the light fixture? It's gone so Peter can fly around the ceiling, but it's back again in later shots.

Continuity mistake: When the dentist wants to put Nemo in a bag, it's a resealable one with a seam at the top. When he finally catches him, it has changed to a normal plastic bag.
Visible crew/equipment: When Tom and Dylan are hanging from the chandelier, there is a shot of the ceiling showing the chandelier coming loose. Then when it cuts back to Tom hanging from the chandelier, in the background behind him is a crewmember holding a boom mic. (00:24:15)
Factual error: In the scene where the kids are viewing the cupcake baking, there is a sign in the corner reading "laugh". The sign is facing towards the chef, when it should be facing the crowd. (00:31:40)
Continuity mistake: The way Tess holds the notepad, to show grandpa the message, changes between the shots. (00:11:30)
Continuity mistake: When Barbara Anne's owner comes to the door to talk to Owen, she is holding a coffee mug by the handle. The next shot shows her holding the mug on the other (non-handle) side. (00:05:50)
Visible crew/equipment: In the scene where Buddy and Michael are leaving the school, a crew member is visible in the bottom left of the shot. At first, he is just standing there, but he then tries to hide inside a doorway. (00:52:00)
Continuity mistake: Look at the scene where Chanel and her mom are putting on face cream. In the wide shot, Chanel only has cream on her chin, cheeks and forehead. Her mom hasn't applied the cream. In the close-up (when her mom says that they might be moving to Paris), there's cream all over their faces.
