Continuity mistake: When one of the thugs stabs the attorney at the Glass House, you see no blood on the knife. In the next shot you see the man wiping the blood off the knife. (03:17:25)
Continuity mistake: When Rhett tries to take Terry's car keys while he's drunk and asleep on the couch, Terry's hand is lying on the table between the car keys and a bottle of vodka on the corner of the table. Rhett reaches for the keys, then you see a close-up of his face, and when the camera goes back to his hand, the bottle of vodka has completely disappeared.
Continuity mistake: When Ruby steals the Jaguar and smashes through the glass gate there is no damage done to the car. The Glasses chase after them and catch up at the police roadblock, we can see there is not a scratch on it.
Factual error: In the scene where Ruby and Rhett walk into their bedroom and they find a Nintendo 64 on the ground, Rhett immediately sits down and inserts a game. Within seconds, he's playing a game without even logging in or choosing a level and so forth.
Continuity mistake: At the beginning of the scene where Ruby goes to see her vice principal, only the back of the v. principal's chair is visible and you cannot see her head over it, but when the shot turns around to the front of the v. principal, she is clearly taller than the chair.
Continuity mistake: When Ruby walks to Terry's office to catch a ride home, you can see she walks in with a backpack on her back. When she is looking in the door crack to Terry's office, the backpack is on a table, but when Ruby leaves with Terry, she does not have the backpack with her.
Other mistake: In the scene where Ruby is writing her parent's lawyer an email, there are no cables connected to the computer she's using, and still she's able to get online. She can't be using an airport, because then you wouldn't get the dialling tone.
Continuity mistake: When Terry arrives in the kitchen where Ruby was listening to his conversation, the light on the phone was on. A minute later when he walks out, the light is off again.
