I Dream of Jeannie Cusamano - S1-E13
Revealing mistake: When the shrink locks the door on Tony, they argue and she calls the police. When she finally calms down she approaches the door to unlock it but you can see the door move before she ever sticks a key in it or touches the knob. (00:25:20)
Revealing mistake: When Amanda and Fin are in Atlanta following up on their rape case, they walk past several cars with visible Georgia license plates mounted on the front. Georgia is a rear plate-only state and wouldn't have had license plates mounted on the front of the cars, as shown here. (00:13:30 - 00:16:20)
Revealing mistake: At the end it is not Helen against the filing cabinet - the face is different. Obviously a body double.
