Nativity! (2009)

Continuity mistake: During the final scene of the Nativity, when the baby is born, look at the boy to the right of Mary, he is tipping the candle upside down. When the camera changes shots, he has now got the candle in his mouth.

Trivia: Largely improvised. The actors were told the main points and events of each scene, and would make up dialogue around that.
