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: 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.
