Continuity mistake: When he's called in to see the Captain, Montag wears his wristwatch turned inward (with the face resting over his pulse point). Seconds later, though he hasn't touched it, the watch has rotated itself 180 degrees and is now on top of his wrist. (00:26:05)

Directed by: François Truffaut
Starring: Julie Christie, Cyril Cusack, Anton Diffring, Oskar Werner
Visible crew/equipment: Near the end when Montag arrives at the Book Peoples' commune, he is greeted and ushered into a house. There's a shot from just inside the building, looking out a window towards Montag and his host as they approach. As the POV shifts a little, a reflection of the camera becomes plainly visible in the window glass.
Book Lady: Play the man, Master Ridley. We shall this day light such a candle, by God's grace as I trust shall never be put out.
