Fahrenheit 451 (1966)

Revealing mistake: Near the beginning, Montag puts on the fireproof clothing to use the flamethrower. It's really footage of him later taking off the same equipment played in reverse.

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.

Deliberate mistake: Montag's hair gets intermittently shorter, longer and shorter again (and acquires a "cow lick" that wasn't there before) near the end of the film. (Oskar Werner had clashed with Francois Truffaut and deliberately had his hair cut to spite director.)

Trivia: The monorail had been built in France in 1959 as a test track.

Trivia: In keeping with the theme of no books this movie has no text visible anywhere except the opening theatrical logo. Even the credits are not shown on the screen. The only symbols shown in the movie are numbers, such as the 451 medallions on the fire crews and their equipment. Signs can occasionally be seen in the background.

Trivia: The books seen burning at various points in the film include several of Ray Bradbury's novels (Fahrenheit 451 itself is one of these), as well as a French cinema magazine for which director Francois Truffaut once wrote a movie column.

Guy Montag: Tell me, this uncle of yours, did he ever tell you not to talk to strangers?
Clarisse: No, he did say once if anyone asked how old I was to say I was 20 and light in the head. They always seem to go together.
Guy Montag: Light in the head?
Clarisse: Mm-hmm, loopy, crazy.

Guy Montag: To learn how to find, one must first learn how to hide.

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.
