Continuity mistake: At the airport, Sarah says "She has a camera in her purse, we have to kill her?" As soon as the camera stops panning around, Marvin is visible in the far background holding the pig teddy with the pig's legs facing the two. The shot then cuts to a close-up of Marvin. In this close-up, the pig teddy's legs are now facing the opposite direction.
