Dead Man Walking (1995)

Factual error: Almost at the end of the film, Poncelet is marched to the death chamber, with Prejean's hand on his shoulder. They are led past an open door - which leads to the viewing room, where the witnesses will congregate. Some of them are already in the room. This is nonsense - it is inviting a bereaved relative to attack the condemned man. In fact the corridor to the death chamber goes nowhere near the witnesses' area, and Prejean would have had to have been escorted back through two guarded doors to reach it.

Matthew Poncelet: Hitler got things done.

Trivia: When Sister Prejean is back at the convent after Matthew's appeal is denied and his death sentence has been determined to go forward, she is playing games with some kids. A playing card is tossed her way, which she grabs and exclaims "Look! I got an ace!" In fact, the card she's holding is the ace of spades, commonly referred to as "the death card" - a not so subtle pun.
