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: During the "We Don't Talk About Bruno" sequence. Towards the end when they are wrapping up the song and the family was circling around Mirabel. The animators accidentally added the "gold fish" woman instead of Dolores. When she leaves the scene for a split second they add her to the sequence. (00:49:16)
