Continuity mistake: At the very end of the movie the 3 girls are performing on stage. Agnes is wearing white tights, but after the platform raises them all above the house she no longer has tights, just bare legs.
Trivia: During the scene in which a minion is standing behind a record deck, on the front left of the deck is a logo not too dissimilar from the Blu-Ray logo, but for the use in this film it was edited to read as Gru-Ray.
Trivia: Throughout the movie, you can see Dr. Seuss's Lorax character imprinted on Margo's shirt under her jacket. This movie was made by Universal Pictures and Illumination Entertainment, who then went on to make The Lorax.
