Wizards of Waverly Place (2007) - 15 mistakes in entire show

Continuity: In the first episode where the Emergency Wizards appear, you can see that the Goblin has 4 legs. Every episode after that with the Emergency Wizards in it, the Goblin has 2 legs.

Revealing: When Alex's uncle comes to visit, Alex and her uncle are in a scoreboard watching a basketball game. Alex's uncle says a spell where everyone's head spins around, and you can see they are fake heads.

Continuity: In "Beware Wolf," Justin's shirt changes from the park, where it is a checked shirt, to his house, where it is a striped shirt, and again from his house back to the park.

Continuity: In "Beware Wolf," Justin messes his hair up (spiky and brushed back) after dunking his head in the potion, but in the next shot his hair is all flat and down again.

Continuity: In the episode where Alex tells Harper she is a wizard, when Harper is eating the kettlecorn, she drops it on the floor. In the next shot it vanishes.

Plot hole: In the episode "First Kiss," Justin has a girlfriend, Miranda. But eight episodes later, "Pop Me And We Both Go Down," Justin starts dating this new girl from his class, who's actually the same Miranda. This doesn't make any sense. How is she a new student and how could they just meet if they were dating eight episodes ago?

Factual error: When we see Gigi and her gang walking down the hallway, their hair is blowing backwards behind them. Yet the fan is in the wrong position (behind them) and therefore their hair should be blowing forward.

Continuity: When Alex's mother is telling Alex that she can help Grandma with the chickens during the summer, she tosses Alex's hair back and we can only see Alex's back with the hair. When the camera pans immediately after, it shows Alex's face and her hair back where it was before her mother moved it.

Factual error: When Alex spills a little chocolate, there should be a small puddle at her feet. But in the next shot, there is chocolate stretching right to the other side of the room. There is no way that the chocolate could have spread that far.

Continuity: Paulie Litt's character is called Frankie, but the end credits have him listed as being Joey.

Continuity: After Mrs. Russo puts Justin and Max in the lair, she is wondering if she should put the big lock on the door or not. She decides not to and puts the lock down on the counter. Two shots later you see the lock is back on the door, but unlocked. You never see Mrs. Russo put the lock on the door.

Continuity: When Harper makes all the apples fall down, there is one more left on the stand. When it switches to Alex and then switches back to the stand, there are no apples on it. In the next shot the one single apple has reappeared back on the stand, then disappears again in the next shot.

Plot hole: We know that the Russos have kept Dragon. But in later episodes, he is never mentioned or seen.

Continuity: Shortly after changing Max back into a human, the three kids stop to talk. As soon as they do, Alex's hands change position from by her side and touching a table to folded in front of her.

Continuity: The red dog carrier containing the "blow-dried rat" dog appears out of nowhere shortly before the dragon seller appears with his own identical dog carrier.
