Revealing mistake: When Annabelle is skiing at the end (just before she turns into Ellen) we see a shot of her from the back of the boat. Its obvious that she is skiing against a backdrop cause the water is too far down for her to be touching it.
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)
