Continuity mistake: On the bus, after collecting her coins, Annabel walks back to take a seat with her friend. As she's pulling on her sock, she notices her foot is dirty. Then there's a cut to a closeup of her sole, showing a slight smudge, as she (her mother) comments on how dirty the sock is anyway. Her foot is much, much dirtier in the first shot and in the one following the cut. (00:22:05)
Revealing mistake: On the bus with her friends, when Annabel pulls off her sock full of change, the coins fall from behind her, not out of her sock. It looks like the "driver" dropped them just as she pulled it off. Clever way to get a tough shot. Her sock is also rolled the opposite way from how it should be. To help her get it off better, probably. (00:21:35)
Revealing mistake: When Mrs. Schmauss is on her bike, holding a wheelie and spinning after being almost hit by the car, while the other bikers are passing by, a support holding the bike up is visible. (01:29:01)
