Continuity mistake: Near the start, Mirabel is given a basket with items such as bucket and spade, windmils etc. When given the basket the buckets are towards her. When the shot changes the buckets are away from her. (00:07:15)
Continuity mistake: The little kid gives Mirabel the door knob, she looks at it and then the two of them come closer to the door but where is it? Neither of them have it and then Mirabel has it again.
Continuity mistake: During Bruno's rap in All of You, when he is talking to Pepa the camera spins and you can see Abuela Alma standing to the left of Julietta, but a few seconds later when he goes to Julietta, Abuela Alma is nowhere to be seen. Julietta has also moved a few feet from in front of the arch door to the half collapsed wall.
Continuity mistake: When Mirabel is talking to who she thinks is Dolores, the stack of donuts on the plate swaps position. The top donut is either at an angle or is flat on top. (00:31:10)
Other mistake: After Mirabel places candles in front of everyone's door, she stops to look at the wall of photos which each depict members of the family standing in front of their respective doors. In the photos, you see each member of the family as a child in front of their door, but the door they're standing by depicts them as adults. When Antonio gets his door, the door shows him as a child.
