Continuity mistake: When the girls kidnap Goldie's dad they walk out of his house and to the Jaguar with keys in hand. The shot gradually switches to an overhead shot as they walk to the car. But even before they get in, exhaust can be seen coming out from the Jaguar indicating it is already running. After they get in, the sound of Maddie starting the car can be heard, even though it was already obviously running.
Continuity mistake: Legs starts to climb up the bridge support with Maddie's art bag. Legs has left her backpack on the ground next to Maddie. After Legs climbs up a bit and tells Maddie what her name is the shot switches to looking down at Maddie and the backpack is gone. When Legs gets to the top of the bridge and Maddie asks her what she is doing, the backpack reappears.
