The film's closing epilogue states: "Two years after Henry Brubaker was fired -- 24 inmates, led by Richard "Dickie" Coombes, brought suit against Wakefield Prison. The court ruled that the treatment of prisoners at Wakefield was unconstitutional and ordered the prison be reformed and closed. The governor was not re-elected".
After leaving the prison board meeting, while speaking with Lillian Gray in the Hilton Inn parking lot, Brubaker claims to have locked his keys in the car. Lillian Gray then opens an unlocked passenger-side door (humiliating Brubaker).
At the conclusion of a previous scene, when Brubaker is leaving for the prison board meeting, an angry Dickie Coombes slammed his hand down on the passenger side door, locking it (the camera is focused on this action).
