The Last Castle (2001)

Continuity: The inmates build the wall using mortar to strenghen it. In the following scenes after the wall has been knocked down, there isn't mortar attached to any of the rocks.

Continuity: In the scene where Robert Redford first assembles the prisoners in formation, right after they finish their fake salute, the shot changes to a view of Gandolfini with a reflection on the window in front of him. The reflection shows the men already heading towards the mess hall. In the next shot, they are all still standing in formation and leave only after being told to do so.

Factual error: Robert Redford is forced to carry a pile of rocks. When he removes his shirt to reveal battle scars you will notice a cheering inmate to his right holding a wooden cane. This is not possible in a maximum security prison since it could be used as a weapon.

The Last Castle was filmed in Nashville Tennessee from March through June of 2001 at an old abandoned prison facility in the northern portion of Nashville.
