Continuity mistake: The scene with the two young detectives driving the crack mother of the missing child starts out with no rear view mirror on the windshield and no one wearing their seat belts. Then the driver has his seat belt on for one shot then it is gone again. The rear view mirror appears back on the window at the end of the movie.

More questions & answers from Gone Baby Gone





Answer: A real life problem with abducted children, especially those abducted at such a young age, is that after a short period of time they begin to grow and look drastically different than when they were abducted. Amanda could have been home schooled for some time and passed off as the adopted child of her abductors to the general public after a relatively short amount of time. Unfortunately, the average person would likely not even recognize Amanda if they saw her out in public.
