As is true of most film adaptations of popular novels, the film Fahrenheit 451 and its corresponding novel are distinct from each other, most notably that the film excludes certain details or events that the novel has.
The film was directed by François Roland Truffaut a French director, actor, manager of production, script designer, and an avid criticizer of films. He was born in February of 1932 in Paris, France, and although he died at the age of 52 in 1984, his career was ridden with awards and accomplishments. Truffaut was star in the French film industry and worked on countless films, helping to propel himself to the spotlight and winning him international acclaim. The film Fahrenheit 451 was the first time he made a film that was in color and the only time he created a film that was only in English.
One result of the director's influence is the language and dialogue of the film. Truffaut took the main role in the creation of the script of the movie. However, English in France was not that common, especially during the time period he had grown up in, and as a result he hardly spoke any English. As a result, a lot of the dialogue included in the film can be found to be confusing or stiff, a sentiment that Truffaut expressed himself during and after the production of the film.
Another result of the director's influence was the fact that the central, driving purpose seems to sway between two distinct mindsets. This is due to the intense disagreement between the main actor Oskar Werner and the director Truffaut that took place during the production of the film. Due to their disagreements and Truffaut's bouts of indecisiveness, it is evident in the film that the storyline doesn't follow one central theme. Truffaut kept a written record of his workings with the film, and movie historians found paragraphs upon paragraphs where Truffaut wrote about this difficulty and how it affected the film.
