The biggest differences between the new film and the book appear to be with characters. For starters, Montag's lazy and mundane-brained wife Mildred is nowhere to be found in the movie.

The most significant difference between Truffaut's adaptation and the novel is that the film portrays Montag and Clarisse falling in love, and Montag helps Clarisse escape the firemen unharmed.
