The film's credits are spoken, not read, in keeping with the film's theme of destruction of reading material.
According to producer Lewis M. Allen, François Truffaut and Oskar Werner hated each other by the end of filming. For the last two weeks, they didn't speak to one another.
Producer Lewis M. Allen said the studio's legal department requested that only books in the public domain be shown burning, for fear of being sued by offended authors. Director François Truffaut and Allen ignored the request, believing that anyone would be flattered to have their book included.
Oskar Werner cut his hair for the final scene to purposely create a continuity error. This was due to his hatred for the director.
The location filming of the final sequence with the "Book People" took place in poor weather. It was hoped the weather would improve for the final days of shooting. Instead, they discovered that it had begun snowing during the night. The presence of snow in the final shots were an unplanned contribution to the film's memorable ending.
