Revealing mistake: In the wizards versus werewolves special, it's painfully obvious Juliet is a stunt double when she fights and grows her wings.
Continuity mistake: In the episode with Alex at the art museum and Justin a teacher's assistant, as Alex is in the room with all the paintings, she puts a piece of rope around the door handles. Later on when Alex says, "Go ahead scream panic," we see Alex in front of the door, but the rope is gone, but the next time it shows Alex the rope is there again.
Continuity mistake: In the first episode where the Emergency Wizards appear, the Goblin has 4 legs. Almost every episode after that with the Emergency Wizards in it (except the episode "Harper Knows"), the Goblin has 2 legs.
Continuity mistake: 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.
Continuity mistake: When Max is filming his last dangerous stunt, the camera changes position in the background between shots.
Revealing mistake: 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 mistake: In the "Wizards vs. Werewolves" special, just as the Russos learn that Alex and Mason have gone to Transylvania, Max is playing on his Nintendo DS. He then flips it shut. The shot switches to Justin, Jerry and Teresa. They talk and the shot switches Back to Max, and you see him flip the Nintedo DS shut again.
The Crazy Ten Minute Sale - S1-E1
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.
I Almost Drowned in a Chocolate Fountain - S1-E3
Continuity mistake: 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.
I Almost Drowned in a Chocolate Fountain - S1-E3
Continuity mistake: 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.
New Employee - S1-E4
Continuity mistake: Paulie Litt's character is called Frankie, but the end credits have him listed as being Joey.
Continuity mistake: 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 mistake: 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.
Continuity mistake: 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.
Continuity mistake: 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.
Pop Me and We Both Go Down - S1-E10
Continuity mistake: In the episode "First Kiss," Justin has a girlfriend, Miranda. But in this episode 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?
Pop Me and We Both Go Down - S1-E10
Visible crew/equipment: When Alex tells her dad she found the trophy man and her dad first walks into the room, you can see a microphone in the top of the frame.
Continuity mistake: They learn the miriana animata (make an inanimate object come alive/walk/talk) but in episode 10 they already learned this one. Alex made Justin's pimple come to life (EP 10), so why was she so confused in EP 19 about how if it gets feelings, she can't make Manny the mannequin inanimate again? Her, Max and Justin (to an extent) made it as though they never learned this one or had troubles with this spell.
Quinceanera - S1-E20
Visible crew/equipment: When Alex and Jerry are doing the father-daughter dance, a pink microphone cord is visible in Alex's veil.
Beware Wolf - S2-E2
Continuity mistake: 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.
Answer: Honestly I've been confused too. Thought the ones going down went to Justin's bedroom or to the station. Then the ones out the door went maybe to an elevator to those stairs I guess. Then the one to the side went to the lair But the freezer also leads to the lair or a secret spot sometimes too.
I think the ones in the sub shop go right up to a hallway in front of the loft, then the ones in the lair go to the bedrooms upstairs. Now there's a way to get to the lair from the loft and I believe it would be past the kitchen down to the hallway where we don't really see except in like one episode. Now what confuses me the most is the lair because when Harper finds out you see Alex using magic to open it into the lair but in every other episode you open it and it's the lair.
