Continuity mistake: When Valerie Vomit is about to steal the Pepsi truck, we see the driver standing behind the truck. In the next closeup we see a cord attached to his pants and the truck, which, as a result, rips his pants off as Valerie speeds off with the truck. Yet in the shot previous to this, there was no cord attached to his pants or the truck. (00:29:20)

Continuity mistake: When Fanny and Billy are talking in his club about the possibility of Fanny performing some of his songs, Fanny is smoking a cigarette held in a long holder in her left hand. There is a shot change, showing Fanny from the back for a few moments, then back to a front view. Her cigarette holder is now gone, and the cigarette is in her right hand. While there might have been time for her to remove the cigarette from the holder and transfer it to the other hand, when the camera is showing her from the back, she is holding completely still. She would have made at least a slight motion if she were removing the cigarette from the holder and switching hands.

The next shot is Cassie dancing, then the next shot is back to Zach, and this time his hair is combed nicely down.
Continuity mistake: When Anna's singing "The next right thing" she puts a bag on her shoulder, with the strap on top of her hair. After the camera spins round her, her hair is suddenly on top of the strap. This bears a strong similarity to the mistake in the original Frozen where Elsa's hair passes through her shoulder - might be a deliberate nod, or else animating hair around objects is difficult enough that shortcuts are often taken.
